[ltp] T42 radeon 7500 crashing - vesa driver better but wont power off display

[Dave Wood]

To sum up. The past few days X has been crashing a lot. I can fix that by
using the vesa driver but for some reason power management of the display
will not work - not even 'xset dpms force off' will work.

So two problems. First I can't find anything helpful with the Xorg log - at
least googling hasn't found anything specific. I haven't made any updates
to the system except security fixes and nothing connected with X. Slackware
12.0 by the way.

I can't find any info on why vesa won't power off the screen. I dont
*really* need to use radeon - vesa would be fine - but I need find out what
is wrong with power management if I'm going to use it permanently.

Hope someone here has some ideas where to look and what to look for.

Cheers
