Lionel, I deleted ~/.gnome2/totem*, and as for gconf, I don't know how to safely reset totem's defaults. Anyway, what does "gconftool -g /apps/totem/contrast" show for you? When I reset to defaults, it's 32767 here.
It may be due to a) it's not fixed on 8xx chipsets, or b) You're not running Feisty, so our environments are different. -- totem overrides XV_CONSTRAST to wrong default value (Xv movies on i810/i945 have horrible colour/gamma) https://launchpad.net/bugs/32963 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
