Recently my wife closed my laptop folding down the screen. When I reopened it, it remained dark. Since the computer was connected to other computers by NFS, I could see that it was still running.

The only way to have a light screen again, was rebooting the computer. Is there a better way to revitalize a sleeping laptop?

Thanks in advance and kind regards, Wolfgang

Are you sure it was JUST DARK, and not hozed? Using keyboard there are usually functional keys to brighten up the display. (On mine its Fn+Up-Arrow, ymmv). However I have seen it appear to be "dark" but ssh-ing in from another machine reveals that it is having a problem restarting some portions of the x server. There is a barely perceptible flash on the screen. Via ssh I can see the following looping messages in /var/log/messages which I have been researching for some time.

This will go for a long time, and then I finally reboot the machine. My machine is using the radeon driver from the 12.3 opensuse install for a Dell Laptop AMD x1400 card. Some searching on the net suggests that Mesa 9.1 solves this, but I have yet to dig thru factory to find that version, (and I'm not yet certain this is a Mesa problem). In all other aspects this (somewhat ancient) card works well with 12.3, but a long suspend will cause this mess. (A short suspend - few minutes - seems to recover ok). Your message on opensuse was a few days old, so I am replying direct as well as to the list. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
