[opensuse] Login screen shows remains of session
Hello listmates, I have a weird problem with the KDE4 login manager. I am using openSUSE 11.1, with KDE 4.2, but the problem also existed on KDE 4.1. I am running the NVIDIA proprietary driver with a Twinview setup (dual monitors) The problem is that the secondary screen shows left-overs or artefacts from the last running session. They also show up briefly on the primary screen after logging in but before the session is fully loaded. I sometimes also see a brief flash of them before the screen saver shows the "unlock" dialog. What are shown are basically snippets of what was shown on screen during the previous session: bits of a web page, a small part of an image file, an icon, parts of a menu, parts of a screen of game that was running under wine. Some of these left-overs repeat, some don't. It's hard to describe, and I don't know how to provide a screenshot of it. This behavior was not present in openSUSE 11.0, with KDE 4.1, and also not in openSUSE 11.1 with KDE 4.1. So I am assuming that it has something to do with KDE 4.2. At one point I thought it was due to files in the thumbnail cache (~/.thumbnails). So I cleared the thumbnail cache, but this did not change the problem. Killing the X server at the login screen also doesn't solve the problem. When X restarts, the problem returns. It almost seems as bits of a memory buffer are somehow shown from somewhere, but I have no idea form where. I could not find a bugzilla, but I am not sure I should file one, since I am using the proprietary driver from NVIDIA. (I can test with the open source driver before I do that, obviously) So first I'd like to know if someone has similar experiences, what might be the cause and what might be done. It's not a huge problem for me, since I am pretty much the only one who uses that system. But it might be a problem on a shared computer, since it might show things that the user doesn't want shown... Any ideas, anyone?

I can report the same thing here, on an almost identical setup, except that it only occurs on the right hand side of my primary monitor, which is widescreen. My secondary monitor is 4:3 format. I would describe the effect as being similar to those screensavers that break the screen into small tiles, except that, as you say, each tile contains a view of a different session/application/document. I only notice it when I reboot, which isn't often.

Same thing here, but on a single widescreen setup, and it happens on more than reboots, even logout in login will cause it.

Yes, that's what I see too. Every logout/login shows the phenomenon. -- "When you just want a system that works, you choose Linux; when you want a system that just works, you choose Microsoft."

Hmm. On re-testing, yes I also get it on logout/login. It would be interesting to know if ATI cards display the same behaviour.

Hi, I think that the problem is with EXA accel. method. (NVIDA drivers can use EXA??) In openSUSE 11.0 the default accel. method was XAA, but now is deprecated and we switch to EXA. You can test changing to XAA (just for testing because it is not supported anymore) to see if you still have these wird things in the screen. This pass me all the time at loging with my intel graphic card. I have submited a bug report about two months ago about this. https://bugzilla.novell.com/show_bug.cgi?id=464512 Rgds.
