Some problems with ATI Mobility 4 display
Last modified: 2007-04-18 12:33:01 EDT
Description of Problem:
Closing down KDE blacks out the screen instead of graying it (the way it
works for all other graphics cards I tried).
Running nedit (from powertools) causes everything in the nedit window to
flicker (works with all other graphics cards I tried).
Nice excuse to have them buy you a new notebook, Mike. ;)
Quite honestly, I currently have zero use for a notebook, and while it might
be a nice toy, I would not want to take advantage of company resources just
for a single bug like that.. ;o)
What would be more useful (and cheaper) would be a joe blow run of the mill
motherboard with AGP 4x on it. Then I could use my Mobility M4 AGP
engineering sample from ATI. I'd also have another mobo for testing with,
so it would kill 2 birds with one stone. I'll have to talk to pb about it
I think the 4.0.99.x code might solve numerous problems like this though.
Hold tight and cross fingers for 4.1.x RSN.
Another M4 problem: If you enable "Fade in tooltips" in KDE, they'll fade in,
but turn all black when they're supposed to be ready. (Doesn't happen on any
I'll check out if the current CVS fixes this when I have the time.
I think the fade in tooltips is a bug in KDE myself, as I have it disabled,
but it remains enabled. Fade in tooltips sometimes fades in (despite being
disabled), and sometimes fades in and then turns black as you describe. This
occurs on r128 cards and Radeon cards. I haven't tried others yet. It is
definitely not tied to just the M4. That is most likely a separate bug though
wether it is in X or KDE or Qt.. We'll have to investigate it deeper...
Pinging to see if this still occurs in 7.3 and/or rawhide.
Closing bug CURRENTRELEASE, assuming it works now. Please reopen
if problem persists.
