dpkg-reconfigure xserver-xorg keeps a setting in the debconf database "xserver-xorg/config/device/driver" to remember which driver has been detected or chosen. You can look at the /var/cache/debconf/config.dat file, but I wouldn't recommend to modify it manually. If you run dpkg- reconfigure without -phigh you should get the choice of drivers and you can choose vesa.
The best way to see if this still is an existing bug would be if you could try a recent live CD and see if it chooses the vesa driver and sets up the correct sync ranges. -- gdm greeter crashes when X is using vesa driver https://bugs.launchpad.net/bugs/138718 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
