The following is original (published from LinuxSir.com):
Most of the red flag forum and refer to my original b version of post:
1. Desktop version 4.0 official version created in the startup management in the control panel is unsuccessful.
Please use characters. There is a problem in the control panel, there is a problem, we will solve it as soon as possible. This is a formal version of a bug, put the disc in turn to re-boot, you can create a boot disk. Patch download will be provided.
2, multimedia player cannot play the .dat format file on the hard disk.
The official version has solved the playback of Win partitions on MOUNT. MPG format file. The method is to modify the extension of the .dat file to. MPG playback (so on the Linux partition).
3, press CTRL-ATL-F4 ~ F7 without function.
It is caused by the red flag to reduce the number of characters terminals. You can restart your computer after removing the # key by modifying the file / etc / inittab.
4, the keyboard seems to start the default is not open by default, how to set the boot automatically open the keypad?
The status of Numlock when you start KDE can be modified by the control panel. Specifically: Control Panel ---- System Configuration ---- Keyboard.
5, when starting and closing the system, you cannot see the blue sky and white clouds, only a few English characters, but the system can log in to the KDE window, is it normal?
When you start shutdown on a single machine, you cannot see the graphic screen, show BF errors, such as running on the 845GL motherboard of the integrated graphics, does not affect the normal use of the system.
5, the official version of the startup and running speed seems fast, the user reflects the speed of speed because of loading, detection, activation hardware, such as setting the network to DHCP speed, will be affected. However, the release is not changed, it may provide Patch download, and the relevant techniques take a period of time.
6, purple light is more than the previous version, but there is a small bug sometimes knocking in the character.
7. "Other Tools" of "Software Package Manager" There is a "update system" to directly Update the system. This feature is very practical, it is really good. If the red flag can make a prompt to a prompt like RH, it is more convenient.
8, input method 4.0 desktop version has full fight, intelligent full fight, purple light, five strokes, Zheng code, you can also add input methods to the input method of the control panel.

Turn the page with a comment and comma. The Chinese desktop will do the input method, which will be positioned over the input method of Windows.
12. Chinese punctuation and Chinese symbols are still not full, to be used in office, how can it?
That's right, this is quite annoyed. For example: The name of the book cannot be entered in the five pen, to switch to the violet. Other some, for example, the permanent permanent percent sign, which is not allowed. The code table file download may be provided with a symbol input method. However, Chinese punctuation and Chinese symbols are used in office and can be solved by inserting symbols in office software.
13, I just finished the red flag 4.0, after restarting, after entering the "system is starting", the screen is invisible, every time a few seconds, please help me.
The refresh rate is too high, decreased to 75, the configuration command in RF4.0 is Xconfig, you can configure the graphics.
There are three start options, one is normal mode, one is a security mode, one is a console mode, enter console mode, then log in, delete /etc/sysconfig/video.old, restart. At this time, the system thinks that the first startup will re-identify the graphics, write a configuration file, and use the 800x600 resolution, the 16-bit color depth, and the default is optimized. Refresh frequency. After entering, modify the resolution and the color depth. 14. Mozilla multi-open a few browsers will have a dialog box for selecting the configuration file, often unable to enter Chinese characters, not to restart Mozilla can solve.
BUG, the next version will be corrected.

20, the Linux graphical interface is very memorable, far more memory you eat! Like QQ, don't look at QQ head, eat memory is 20m, so 128M memory machine runs too slow.
Now the memory price is general, you can upgrade memory to 256M.
21. What software is integrated in the RF4 software tool disc?
There are also some software in the tool disc, mainly: Phoenix, KDevelop, etc. Development Tools, OpenOffice, MPlayer, QCAD, GIMAGEVIEW, Bevolution, and some games, education software. A total of 650M.
(1) Bowser-Internet Phoenix - a great Internet browser.

Setting the RealPlayer plugin in the Konkueror browser to see the embedded movie!
24, Hongqi R & D: Regardless of R & D, maintenance or testing, teams are quite large. Have the opportunity to welcome the Hongqi company to visit.
25. The red flag RF4.0 desktop is beautiful and does not beautify it.
26, 4.0 Official version of the resource manager, the navigation panel cannot display the root directory, what is the reason?
Regarding the problem of root directory, it is actually modified after consideration. Because the general user does not need to operate the root directory in the Explorer. And it is possible because it is not familiar with the Linux system, causing misuse. So remove the path of explicit access root directory. If you need to access, you can use the up button to return to the root directory. Of course, if it is frequently accessed, it is some inconvenient.
27, Hongqi 4.0 Is there a Chinese usage manual?
Users downloaded from the Internet to install ISOs into the virtual drive, you can see the manual (PDF format) in the Manual directory.
28, don't like the white bottom, have the terminal changed?
Like white can customize colors. In fact, the terminal is running the RXVT command, which can be added with the option.
RXVT -RV -BG Blue -SB -SR -SL 3000-TN VT100 -TITLE TITLE_NAME -E RLOGIN-8 HOSTS
-RV screen reverse display, inverting the color set when the compiler is compiled.
-BG background color
-fg prospect color
-SB supports vertical scroll bar
-SR support horizontal scroll bar
-SL save how many rows of screen contents (may be equivalent to the size of the buffer)
-TN simulation terminal type
-title set the title name
-e The command executed when the terminal is started
29, the cursor of the Pinyin Pinyin followed in OpenOffice?
OpenOffice is a third-party software we do not provide support.
The cursor follows the problem because the overall desktop is using the KDE environment, so there is a case where GTK writes (such as OpenOffice, Mozilla) is not supported. There is really no good way to do it.
30, I am in VMware 3.0, 3.2, but I can't start XWINDOWS in the installation, I can only install the text, there is always an error generation.
VMware cannot support correctly. You can use VMware in 3.2 to install 4.0, which cannot support graphics installation. The graphics installation may be the gramebuffer that the virtual machine simulation cannot support FrameBuffer. Installing to the last error, it may not be tried in addition to you, do not know the specific situation. However, the technical note does not mention product support, let alone VMware does not have source, even if we find problems, it is difficult to solve, so I think even if it is reflected to the test department too much.
32, I really like the style of winxp in 4.0beta version, is there a way to replace it? (The official version is not completely XP style)
We only provide these styles, you can go to the KDE website to find www.kde-look.org.
The XP style is used in the original beta, but considering copyright issues, it has dropped this style. And if you have downloaded the same copyright issue on the website. This style can be downloaded online, as for the specific location, perhaps technical support personnel are indeed unclear. If you like this style, you can install 4.0bata, then install the official version. Do not format / partition when you install, you can keep the BATA version of the WinXP style (unreasonable).
33. What are the software for RF4.0 default installation?
The default installation software mainly: kghostview, gimp, pixie (image browser), screen screenshot program, scanner, plotting program, CDBakeoven, CD playback (KSCD), MP3 playback (XMMS), KXINE; StarCraft Translation kings, Mozilla, Kmail, GFTP, GAIM (no QQ support); there are some terminals, something such as disk formatting.
34. I installed the desktop 4.0 with the test version.
(1) Allow a block to bind multiple IPs when configuring the NIC, and can support the IP forwarding function of the advanced gateway, so you can use a desktop 4.0 to access several clients.
(2) Plus a "Update System" tool in the "Package Manager" in Control Panel, you can download some patch they provide on the Red Flag website.
(3) You can add multiple Linux boots in the "Startup Manager" in Control Panel, as long as the partition you want to add, you can, the kernel version and the initrd file can be automatically detected. No need to modify the GRUB file directly in the command console.
(4) Previous test version 4.0 When printing the PDF file, it cannot be transferred. Sometimes it is full of paper. Now when printing, the printer editor will appear, in the "Properties" - "Filter" Out a "PDF" writing, so that the PDF file is printed is normal.
35, 4.0 official version without Java virtual machine?
No! A Java virtual machine is required to download and install.
36. Our company uses a red hat to share the server's server, and the computer uses me, and uses Linux, one of which uses RF4. I don't know how to get a problem, in the servo Samba / Public Get a strange name, there is "(" ("this symbol, can't be cleared in ME, can't be cleared in the Red Hat, because there is that" ("inquiry. But actually getting a point in RF4. !
Engineers spent some Kung Fu in order to solve these illegal characters.
37. How did the desktop version 4.0 hardware compatible program list have not yet?
Sword: Already finished, you can see / download on the website immediately. Since compatible testing is continuously extended, the list of current sorting / submission does not represent all compatible results. For reference only.
38. How is Linux4.0 How about the hard disk installation?
You want to download

(1) The extension of the file is. Rpm
On the terminal zxvf:
RPM -UVH * .RPM (Enter) Follow the commands to complete the installation package. Of course, you have to run under the path where the package is located.
Linux also has a "add delete program". There is something called a package manager under the control panel, usage similar to Windows.
Go and try it.
(2) The extension of the file is tar.gz
Execute it under the terminal:
1. Unpack file:
In the directory where the file is located
Tar-xvzf * .tar.gz
2. Enter the despicted folder and prepare to compile:
./configure
3. Compile:
Make

57. The system has installed WIN, how can I install the RF4.0 desktop version without losing WIN?
The last partition is backed up, then uses the light-up, enter the installation interface, according to the system's prompt, part of the last partition is used as the exchange partition (swap), which is generally twice the memory, and then separates the other part as the root. Directory, generally 4G left and right sizes are suitable, and the rest is returned to Windows. (Win Magic Partition Master rebuild partition)
Next, follow the prompts, click Next until the installation ends.
The general case is typically installed. If you need to install other packages, you can install it after installation. If the machine's configuration is relatively low, the system may automatically enter the text installation interface. If you want to speed up the installed speed, you can enter the text after boot when you start, you can enter text installation interface.
How does the 58, 4.0 desktop version not comes with RedOffice?

This phenomenon is probably because LILO is not installed, so why can the LILO installation are not complete? I don't know if you think about the virus detection on the home version! However, there are two points, one is that the hard disk parameters should generally be set to LBA. It is best that Auto, and it is best to hang the hard disk on the IDE1 Master, or the above is only possible, this is not It is inevitable, that is, there may be the above settings, but their Lilo is good, this is also possible.

65, can you upgrade from 3.2 to 4.0 free?
Regarding the upgrade problem of the old system, due to the 3 series to 4 series, the system version changes relatively large, from the technical statement, the user is not recommended to directly carry out the RPM package upgrade. Reinstall is more appropriate! From a product point of view, it is in principle that old system users are free to upgrade, but the 3.2 series users can purchase the edible price of the education version of the package with the registration card.
Download free from the Internet.
66. What is the medium of the desktop 4 official packaging and desktop 4 educational version? Why launch a educational version?

It is designed to modify the file manager to prevent user malfunction from causing system. Skilled users can use VI from the terminal if they want to operate, or use other editors.
If you log in as root, right-click on the / etc directory,
Then "file protection ...", change to not protect or other protection methods.
Mainly to prevent unfamiliar Linux users from deleting system files, or histed in Windows partitions on a directory.
/ etc The script under the ETC may cause the system to restart or shut down, so use the prohibition of protection from entering
70. Playing with KXINE VCD is the "File" -> "Other" -> VCD. Open directly. Dat file is invalid.
Choosing kxine is mainly considering MPLAYER is not enough now, and Xine upgrades very quickly. Of course, KXINE upgrades are not fast enough. I have tested the WMV file, the MOV file, and the AVI file can play with KXINE.

no difference. Can. You can also use Shutdown -h Now.
89, 4.0 The desktop version is slow, how can the system speed? System speed slow and graphics driver and memory relationship are relatively large.
System speed
(1) Turn on the hard disk DMA support
After the system is installed, the hard disk's DMA is not open. My method is in the last side of /etc/rc.d/rc.local, plus one line / sbin / hdparm -d1 -c3 -m16 / dev / hda every time After booting, the DMA of the hard disk will be turned on and do not have to be manually set.
If your hard drive supports ATA33 can add -X66 this parameter, ATA66 is -X68, like a hard disk is ATA66, then the full parameter is / sbin / hdparm -d1 -x68 -c3 -m16 / dev / hda test, in DMA Before that did not open, the actual read efficiency is about 4.10 mb per second. After the DMA is turned on, the actual read efficiency per second is more than 20 MB of approximately 5 times.
(2) Close extra system services
Just activate a few basic Service Services crones, Network
Syslogd.
Red Flag Linux will only keep APMD and NetWork two services.
(3) Download kernel reprogramming.
The default installation of the system is done for most of the computer, and does not optimize your computer, so it seems bloated fertilizer, because kernel directly controls everything in the computer, so it is of course great.
Download the latest kernel reprogramming, program the hardware on your computer into Kernel, don't make Module, don't program it without any, so that Kernel, you can complete the power of your own environment.
(4) Reduce the number of virtual terminals
The system is 2, 4.0 desktop version has been optimized. Only Ctrl Alt F1 ~ F2, about 4 mbytes memory, but in this way, X-WINDOW will become Ctrl Alt F3 from the original Ctrl Alt F7.
Modify / etc / inittab, plus the # font size of the #nity 3 ~ 6, then the instruction #init q
(5) Adjust the X-Windows environment (under the KDE window)
The number of colors is set to 16 bit, there is a good effect, and 24 bits can't see if there is a waste of resources.
Do not use the screen saver.
Cancel the animation window function.
Try to use the same type.
Don't use Netscape with Mozilla with Mozilla.
Do not activate sound server ARTD
(6) Adjust application priority
Generally, when using any program, its nice value is 0, meaning the use of the CPU. If the usual program has high priority, natural efficiency will be better, the value of priority is from -20 to 19, the higher the number, but to note that the general user can only lower (0 ~ 19), only root has the right to high priority (-20 ~ 19). We can use ps -fel to observe the Ni column.
Half a day, how to adjust it? There is an instruction / bin / nice to be used, the usage is as follows :nice -n program name parameters ...
n The value from -20 to 19, this is manual operation, in KDE, can be set with the menu editor, the method is in front of the [command] of the priority of the priority, plus / add / BIN / NICE - N is OK.
