G'day, I can confirm that I also get this bug, and that switching to a console and back undoes the garbling (thanks for the tip).
The graphics card is an nVidia Quadro NVS 285 $ lspci -vv | grep -i nvidia 7:00.0 VGA compatible controller: nVidia Corporation NV44 [Quadro NVS 285] (rev a1) (prog-if 00 [VGA]) Subsystem: nVidia Corporation Unknown device 0334 The system is a Dell precision 490, running ubuntu edgy amd64. I would be happy to provide more information if it would help, Francis Bond <[EMAIL PROTECTED]> -- Garbled screen _sometimes_ https://launchpad.net/bugs/63995 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
