I too suffered from this issue after the xorg updates in question. My Toshiba Satellite M45-S265 laptop uses an Intel 915GM graphics card. I also stopped experiencing this issue when switching to GDM. I reverted back to the older xorg package versions as mentioned above, which got rid of the issue. I can now use KDM with no errors.
Prior to this, the only way I could still login with KDM was to hit "ESC" when the Kubuntu splash screen appeared, then hit CTRL+C repeatedly after the bootup steps started appearing onscreen. -- after recent update which included xorg, xserver etc causes low-graphics mode error at start https://bugs.launchpad.net/bugs/491483 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
