I met the same problem with M82(RV620). And I find it's the patch: 100-fedora-vesa-1.3.0-mode-heuristics.patch causes this bug.
I have test it the latest git code of VESA driver and other version driver without this patch, all will work. Meanwhile, If I add HorizSync and VertRefresh to the xorg.conf, this bug also can be avoid. Section "Monitor" Identifier "Configured Monitor" HorizSync 31-38 VertRefresh 50-60 EndSection ** Attachment added: "the patch is in debian\patch" http://launchpadlibrarian.net/12754172/%5C10.237.74.76%5Cmusic%5C100-fedora-vesa-1.3.0-mode-heuristics.patch -- [ATI X1300] Could not generate /etc/X11/xorg.conf.failsafe https://bugs.launchpad.net/bugs/174434 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
