ATI -> doesnt want to

Salim87 · 12-03-2005, 04:43 PM

Hi,
I followed the instructions on fedorafaq dot com - but they didnt help.
I've got Fedora Core 4, my Kernel version is: 2.6.11-1.1369_FC4smp
my Graphic Card: ATI Radeon 9800 Pro
Other: Intel Pentium 4 Pro HT
ABit Mainboard

I made:
yum install ati-fglrx kernel-module-fglrx-$(uname -r)
and extended xorg.conf with Option "UseInternalAGPGART" "no" as described at fedorafaq
and everything seemed to work well. But these are the results:

Code:

# fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: Mesa project: www dot mesa3d dot org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.2.1)

Code:

]# fgl_glxgears
Using GLX_SGIX_pbuffer
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  143 (GLX)
  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  32
  Current serial number in output stream:  32

Maybe it has sth to do with agp I think, here are further results:

Code:

Seems that there is no agpgart?? Please help me, what shall I do?

Btw: the stuff with not allowed to link to other pages seems nonsense for me (I couldnt quote www dot mesa3d dot org? But well, there must be sense behind it, otherwise the admin hadn't set that up like that.

It has a nice tutorial and a link

Salim87, what chipset does your motherboard have? Give all the other detailed info of your hardware. BTW this is VERY IMPORTANT: you must update your kernel, or install a new one cause the drivers you installed, ati-fglrx and kernel-module-etc.. don't match! If you look closely to their last digits (displayed in yum) you'll see that they are different and they don't work together. This is an error in fedorafaq.org, if that's where you got it.

What about now?

Salim87 · 12-04-2005, 02:50 AM

Hey yeah. It works now! Yipiieee! I've just used the ATI driver from ATI.com this time. Downloaded the 60MB installer and made what it want of me. And it works now. 4039FPS with glx_gears :-)
BUT: Really cool and strange thing I have now. My desktop is larger than my monitor x_X - and when I move the mouse to the margins, it scrolls. Cool stuff, but I've got good eyes and don't need it. How can I make it normal again?
Please help, dont want to scroll all my life ;-)

Check your xorg.conf in /etc/X11. There must be a few lines like:

Subsection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0 # initial origin if mode is smaller than desktop
# Virtual 1280 1024

Put your virtual resolution equal to the real one. If you don't find it, as root open a console and do cp xorg.conf xorg.conf_works (this backups your config file to the last one) and do one of these:

1 ) adapt the code above in xorg.conf or

2 ) run fglrxconfig and press enter most of the times, it will ask you if you want a bigger virtual size.

If you followed 2) you got a really strange xorg.conf. Go there and or 1) you like the config cause it works so well in everything or 2) you preferred the previous one but still want no virtual size. If 1) congrats, if 2) open xorg.conf as root, copy the desired lines, open xorg.conf_works, paste it there, save it as xorg.conf, reboot. pheww

If there is some sort of error and you get no x, reboot and before choosing the os, press a and write 3 in the end of the line, press enter. Now you get a console, where you type as root, cp /etc/X11/xorg.conf_works /etc/xorg.conf.

batalha · 12-04-2005, 05:27 AM

HEY, I'm not so sure if it's that, cause I never had it, but guessing by the name it can only be right?

edit: I forgot to mention, you should edit the topic name to add (solved) or something

Thank you for your answers very much, but it didn't helped, I still have that kind of "screen".

I've noticed another problem too. Whenever I want to "log off" (to log in as another user for example) or when I press CTRL+ALT+BACKSPACE the screen becomes black and there is nothing anymore. No Console, no login screen, and no matter what key I press, nothing happens. I've to restart my computer manually then. What can be the cause, what can I do?
I appreciate every help :-)

Those appear to be very different problems. Try uncommenting the "virtual" line on that file (the one that starts by #). Another thing, that file was made by the ati driver from ati. It's best to have the default one, the one you get after a fresh install and kernel, and yum install packages.

I forgot, for the last error, do the following:

after crashing restart the computer in text mode (i described the procedure before), and copy your x log to somewhere else. Then we can have a look at it. I solved that problem long time ago, can't remember the solution...

batalha · 12-04-2005, 07:26 PM

WAIT - this very site has a wiki with an ati howto where it says that this logoff issue is a KNOWN BUG! It says it cannot restart x, though you can exit to a shell.

I removed the comment (#) before virtual, but it doesn't make any difference. Still, the screen is bigger than my resolution.
Now what is the solution of this BUG? I can try setting useinternalagpgart to no, but maybe ATI wont work anymore?
