The last couple of days I have had to reboot my Ubuntu-workstation when the screen suddenly goes black. After some seconds I get a pop-up with the message:
Ubuntu is running in low-graphics mode
There is some buttons that tells me I can do different things but whatever I do I end up losing all windows I worked in earlier and having to reboot to get back full resolution.
I have not found any way to reproduce this behavior. It has happened after being logged in for several days and sometimes just after boot and login when I'm starting an xterm and in all time intervals in between.
I also run a default setup of munin on the box, but it shows nothing outside normal behavior.
Ubuntu 8.10 fully updated on a
Dell Optiplex 210L.
- What can I do to prevent this blackness?
- What should I monitor and how to get some useful debug information?
