Hi , guys:

I have a new Acer laptop and I have installed CentOS 5.5 x86_64 bit.

The problem is that there is no driver for the ATI mobility radeon HD5470 and the graphic is so bad!

On amd-ati website I have found the catalyst driver version 10.2 butit seems not to be the correct solution.

The current screen resolution is 1024x768, but my laptop is widescreen and the best screen resolution is 1366x768.

Do you have any suggestion?

Thanks in advance ....

The driver should work:

https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/ati-driver -installer-10-7-x86.x86_64.run

http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx

RHEL 5.5 is among the officially supported OSes.

Thanks for your advice .

I try to use that version but it does not work ...

The error message is the following :

Fatal : Module fglrx not found .. fglrx(0): hasn't established DRM connection ... .. .. Fatal Server errror : Caught signal 11. Server aborting .. (EE)fglrx(0): firegl_SetSuspendResumeState FAILED -9

Did you check if the module is present somewhere?

Hi,

I installed ATI in Debian dozens of times. Just tried the same process on SL 5.5 here few minutes before.

1) linux-cat107-install.pdf from ATI download website says what files you have to have installed prior to ATI instalation/kernel compilation

https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/linux_cat1...

2) Radeon HD 5xxxx is included in the 10.7 list of ATI drivers

3) Installation went smoothly without a problem

4) ATI driver is named fglrx*

5) search for its mutations ;-) there: lib/modules/fglrx lib-/modules/"kernel-sig"/kernel/drivers/char/drm

kernel-sig = your kernel's signature

6) Alas there is not such thing like Debian's modconf to conveniently check/manage installed kernel modules; there is no such file like Debian's /etc/modules with a list of additionally installed kernel modules.

(Perhaps someone hints us how to peep into SL kernel modules?)

7) ATI installs aticccle manager + fgl_glxgears (with 3D rotating cube)

8) You __have to change__ "manually" monitor's VertRefresh and HorizSync data in /etc/X11/xorg.conf file, e.g.:

Section "Monitor" Identifier "aticonfig-Monitor[0]-0" HorizSync 30.0 - 70.0 VertRefresh 50.0 - 120.0 Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection

and add "Modes" line in Screen section:

Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "aticonfig-Monitor[0]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1024x768" "800x600" "640x480" EndSubSection EndSection

9) WARNING :-(

ATI worked good but I had impression that Xorg's latest radeon driver (found in SL 5.5) worked better, especially during MC window resizing - radeon was making less flickering than ATI proprietary driver.

The warning relates to system fonts- ATI changed my system fonts to "something ugly" and in 6 pt size! I use IceWM, but every apps got the same fonts and nothing could be done via IceWM settings, of course. Thank God, I had a magnifying glass at hand...

So said I changed X11 settings to previous ones, namely to SL radeon driver.

BTW. How to change system font in SL? I tried to find out thru google search but to no avail. And there is no such script like system-config-fonts, why?

I hope I were able to help.

Regards

5. search for its mutations ;-) there:

kernel-sig = your kernel's signature

Thanks for your advice .

I refered to the ATI driver installation doc and found the following message :

Note: If a Linux 2.6.11 or newer kernel was built with CONFIG_AGP enabled, the kernel AGP frontend is required to load the fglrx kernel module. To identify whether your kernel was built with CONFIG_AGP enabled, look for CONFIG_AGP=y in the kernel config file, or if the 'agpgart' module is loaded.

And I found that module is not in CentOS 5.5 x8_64 .

So could I compile the kernel that enable that module ?

Isn't it right ? Thanks ...

I solved it by myself .

I tried to try " yum install kernel kernel-header kernel-devel " command to install that packages and then reinstall the ATI graph driver again . This time the screen works well ..

Haaha.....

I found that excerpt too. Anyway the compilation was successful and the driver stable. Try it yourself, you are not going to screw anything. In the need you can alway get back to former radeon driver.

BTW Compiling kernel is rather fun not a scary process.
