Here's the thing; I never had trouble suspending the console, but I also never tracked stable or current with that r128 card in. I only ran releases with updated ports trees. Last time I ran that card was under 4.6-RELEASE and my experience was that I could suspend on the console or another VT but when I resumed if I tried to switch back to X it would hang (mouse moved, but everything else was borked with CPU on 100%). My solution was what I detailed about running two X servers.
I've been running the radeon card since the middle of last summer and now I can't do a suspend to ram at all -- the bios chokes and does a power cycle on resume (guess it doesn't understand the new card as well as it should). I don't have any other side effects and I can still suspend to disk. The suspend changes were only to the radeon driver and they were not merged. I found and tried the diffs; they seemed to work well in that they prevented hangs when switching to a vt while running a DRI app, but I've never been able to test the suspend to ram because of the bios issue. It does not work when resuming from disk -- it displays the behavior I came to expect from the r128 card on resume from ram. By the way, those diffs set up a handler to notice the suspend event and flush the buffer leaving it empty when the machine suspended. The same was done for a switch to a vt to avoid the same sync problem.

I was initally going to say this too. However, I remember I tried to suspend/resume my laptop in the console with DRM not loaded and still had hangs. I put some printf in the kernel to see if the AGP setup was corrupted by the resume and it didn't look like it (having noticed that linux does a whole re-setup of agp after resume). I didn't ever try without AGP at all I think, and didn't try reconfiguring. Some work has been done on suspend/resume with the DRI. I don't know too much about it, but I think it let you suspend/resume while a 3d client was running. I don't remember if that stuff got merged or not (thinking not). I think suspend/resume is supposed to still work if you're switched away to console. -- Eric Anholt [EMAIL PROTECTED] http://people.freebsd.org/~anholt/ [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
