Comment 14 for bug 136853

I can also confirm this issue, unfortunately after moving from Gentoo, to Ubuntu 8.04, I also get the vcons switching issue (which the posted workaround in <a href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-siliconmotion/+bug/144178">bug #144178</a> does not seem to work for me. Perhaps this is because I'm using vesafb, and not vga16fb).

I wish I could be of more use. Disabling DPMS is the only workaround I can think of for the moment. Is anyone in a position to actually debug this and investigate the cause?
