 |
|
I've been struggling for a week to get DVI output on my LCD using the ati-drivers at no avail.Unfortunately I found little help here in the forum
and even if this mini-guide helps noone, this is my protest against all those who yell "Yeaaaaaaaaah I got it working.I'm the man" and not saying how in order to help others.
Finally yesterday I found a way though finally I rejected it returning to analog output.
!!!!This solution is for people not seriously intrested in the high FPS provided by ati-drivres(say,gamers.)
I'm using :
2.6.1-mm-sources
Xfree 4.4.0 rc2(xfree-4.3.99.902.ebuild in portage)
ATI Radeon 9100(128MB)
1:Unmerge ati-drivers and erase(back it up I'd suggest) XF86Config-4
2:In the Kernel configuration, this time specify the DRI module of your Card(radeaon in my case).I used it as module.
3:run xf86config(fglrxconfig does not exist).
4:Modify the created XF86Config adding the changes needed to enable DRI
| Code: |
Section "DRI"
Mode 0666
EndSection
|
| Code: |
# This loads the GLX module
Load "glx"
# This loads the DRI module
Load "dri"
|
And add the performance tweeking options (at the "Device Section")
| Code: |
Option "AGPMode" "4"
Option "AGPFastWrite" "True"
Option "EnablePageFlip" "True
|
If you havent rebooted, modprobe radeon module and startx
Done!
Some notes concerning this configuration:
-Using the above I got approximately 1850 FPS at glxgears(which is not that bad).What was strange,was that,contrary to using the ATI drivers, when the glxgears window was hiding (say behind a console), the FPS were reducing to 82!!!! instead of soaring(I get 2900 FPS with ati-drivers but analog output).Also, when I was writing in gaim, I noticed 200FPS drop.
So I jump to the conclusion that performance is largely CPU usage depended.
-I managed to run flawlessly Enemy territory, but when I tried Return To Castle Wolfenstein the FPS was rather low,making the game difficult to play.
-The graphics quality was perfect.
-I'm not sure if success was due to the new xfree(though R.C).But it seems that the Xfree driver is powerfull though inferior to the ATI one(logical).
-The whole problem with DVI seems to be a driver issue.Maybe the next drives in cooperation with the new xfree will provide the ideal DVI output.
Any suggestions whould be gratefully accepted.
Special thanks:gearheadsmp (forum) ,The_wow(gentoo irc channel) who provided ,no actual help ,but interest and precious time.
