The gamma behaviour seems to have changed in the xserver as this code has not been touched in ages and used to work fine with older xservers. I've just gone ahead and committed a fix to the ddx: 4651d77211b508cb6b76931807780e317f232220 I'm not sure what changed in the xserver. Hi, updating from 6.12.5 to 6.12.6 I have the same problem with my graphic card, ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]. I changed radeon_crtc.c as proposed but solved only partially the problem. I have seriuos problem after hibernate and after switching back to X from terminal (es. CTRL+ALT+F1), all is redish end the image has very low quality, I must restart X. I don't know if relevant, the system is not in KMS. Bye, pingoo (In reply to comment #3) > Hi, > > updating from 6.12.5 to 6.12.6 I have the same problem with my graphic card, > ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]. > I changed radeon_crtc.c as proposed but solved only partially the problem. > > I have seriuos problem after hibernate and after switching back to X from > terminal (es.

Everything works as expected, I do not have any problems swiching to terminal (CTRL+ALT+F1) and back. I never used hibernate, but suspend to ram without problem. My system: Radeon Mobility 9200 (AGP) xorg-server-1.7.6 xf86-video-ati-6.12.6 (patched) Cheers, Sebastian.

You're right, I modified and recompiled the xf86-video-ati and, after, three other packages related and everything is working. Thank you and sorry for posting. Bye, pingoo *** Bug 28901 has been marked as a duplicate of this bug. *** *** Bug 29701 has been marked as a duplicate of this bug. *** There is one remaining problem, as I wrote in Bug 29701 which is duplicate of this: The other problem which it seems for me is related to the gamma is that opengl programs for example glxgears are with wrong colors too on my HD4200 card and is not fixed with the commited fix 4651d77211b508cb6b76931807780e317f232220. The gears are blue/purple and not green/red as it should be. KDE opengl screensavers have problems too - some of them show: *** glibc detected *** /usr/bin/keuphoria.kss: malloc(): memory corruption: 0x087f5d90 *** There must be something different for 16 bit depts, because with 24 bit there is no problem. |
