Using Opensuse 11.1, Intel Atom processor, motherboard with integrated graphics 945G chipset. When I login to KDE4, the screen is scrambled for about a second before the login splash (with progress bar) shows, and then again for about a second when it’s nearly finished.
The scrambling is not completely random. It seems to show bits of old/previous screens from the last session.
I get this too. I’d always assumed it was considered a security risk, and won’t take long to be fixed. If I log into another operating system, then reset into SuSE, I can see sometimes disjointed remnants of the last screen I had displayed in the other O/S. That’s gotta be considered a problem. Haven’t bothered checking for a bug report myself though…
I don’t get this problem using my openSUSE laptop with KDE4, but I do get it on my other laptop which is running Ubuntu with gnome; I also get it on this laptop when I start up from usb using Ubuntu. I didn’t care too much and I assumed it doesn’t do any harm.
Same happens in my laptop that have a Intel GM 965 graphics adapter.
Unfortunately, this is not the only one problem I have with this graphic
card. I have problems with KWin, Compiz, Assualt Cube, Real Player
(when I enable XVideo), and MPlayer (video works fine, but it frequently
get a bit messed in fast scenes of movies).
Searching about these bugs, I found many other people with Intel
graphics cards that have thousands of bugs. This is not only with
openSUSE, but with almost all distributions of Linux.
Well, at least there new drivers for Intel graphics cards that were
released in April that are believed to fix all these bugs (I want believe
in that). The driver is available in Intel Linux Graphics, but
since I am not a Linux expert, I did not try install them yet.
I am waiting for official updates in the Xorg packages, but
I do not know if these drivers will be available in these packages
for openSUSE 11.1. Maybe we will have they working in our machines
only when openSUSE 11.2 be available (I really do not know, but
would like to do).
So, if someone have installed the drivers from Intel Linux Graphics,
please let us know!
You really are unlikely to see a version jump mid release unless it is a security need or an app with show stopper bug any way…
And yes xorg repo does have the fix I updated to it fine but disclaimer I don’t use intel, I did it in vmware… I used zypper dup to make sure it all was lined in well and this is a very clean install with no extra repos beyond 42 and has never seen any of factory.
Last time I told you you came back and said it made a mess but didn’t really explain how or what and warned people off it. It is possible at that moment in time you got unlucky…
But that is the same with any 3rd party/build repos. With these type repos you turn them off you look occasionally you don’t just take the next update that comes along, and certainly not if it is working.
Try changing the Acceleration Type in Sax2 (AccelMethod) to XAA. It should solve the problem. The issue is that the Intel Graphics Driver version being shipped by Opensuse 11.1 uses EXA (which is newer) instead of XAA (older and thus more stable).
That XAA thing worked for me with intel 865G. however, running Opensuse 11.1 until this change(since initial release) was a real pain. Switching to tabs in firefox or scrolling in okular was really slow. I think that people who decide how to assemble a desktop have no ideea how much it hurts, otherwise they would have fix it a long time ago.
Thanks for the tip, anshuljain.
