1400x1050 display, right? I have the same problem on my IBM T30 with the same display and Radeon Mobility M7 LW. A real pain, but possible to recover from (at least on my system) without a reboot. To avoid the problem, try to switch to a text screen (CTRL-ALT-F2) before leaving the display. That will allow you to wake the display and enter ALT-F9 to get back to X. If you forget or can't, switch to a text display (which is messed up) and turn the display off (Fn-F3 on my IBM). Turn the display back on and the display will be back in sync. ALT-F9 to get back to X. This seems to be a timing issue. It looks like the screen wants to be powered on for a bit before the display is driven at 1400x1050. When I wake the display with widows, I seem to notice a delay after the light comes on before the display is un-blanked. This is a guess. The same happens to be after a suspend, but I don't think this is too common and I think it can be fixed by adjust ing a delay in apm.c. But the screen turn-off problem seems out of APM's domain. (Spoken by someone with minimal knowledge of APM.) Hope this helps, and I'd love to find a real fix for the problem. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
