After more tests, I must conclude that xorg for that display adapter was broken again between alpha6 and beta.
Whichever xorg.conf I use from autodetected or adding my a6-working patch to it, the display will fail the way I described (hang or spontaneous reboot). Only If I boot in recovery mode (and choose resume or xfix) will the display work. So, in summary : 6.04: worked beautifully at 1024x768 7.10: totally broken 8.04a: works, but autodetects 800x600 only, needs 1024x768 patch 8.04b: totally broken again I diffed the config I used in a6 with the one in beta after same patch : $ diff xorg.alpha6.conf xorg.beta.conf < Driver "mouse" > Driver "vmmouse" > Section "ServerLayout" > Identifier "Default Layout" > Screen "Default Screen" > EndSection Thanks in advance for restoring working state. -- VIA/S3G VT8623 [Apollo CLE266] display no longer works https://bugs.launchpad.net/bugs/197514 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
