Comment 116 for bug 548709

Unfortunately this problem is affecting me in Quantal Quetzal as well. Basically the behavior is the same as the other fellow users are experiencing: A too light-saturated Desktop Display that cannot be corrected using any gamma utility.

In the past I could fix this using the radeon.modeset=0 variable in the kernel boot, however since the upgrade, if I do that I don't have any display, it logins normally but no image whatsoever. So in order to boot in the system again I should use the radeon.modeset=1 variable again, with the undesirable color side effects. Nevertheless this seems to be affecting the Desktop only, because if I use any OpenGL program, like the Open Arena game, colors shows normal.

Alas I've tried some of the solutions suggested in this thread with no luck. I've attached the dmesg and lscpci logs to this report as the documentation indicates, however if you need more information in order to fix this issue, I would gladly do whatever it takes to see this fixed.

Some basic information for reference is I'm using Kubuntu 12.10 Quantal Quetzal and using an ATI Radeon R100 video card. Using the uname -a shows me this kernel info: Linux 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012 i686 athlon i686 GNU/Linux

I appreciate any help given with this issue and I thank you in advance for taking the time to read this report and try to solve it.

Best regards,
