I am having a Problem with Toshiba laptop display. The display works awesome while booting up and running the KDE desktop the problem happens only when I log out to switch to a new user or if I go into a root console like with ctrl, alt, F1. every thing gets blurry like a TV with static. if I reboot the screen looks good again all the way during boot and on into starting and running desktop. It seems as long as X doesn't change windows all is good. I am running Sidux and have installed latest Nvidia beta driver with smxi script however it does not mater which Nvidia driver driver I try latest or beta both do the same thing. This lappy is duel booted with Windows 7 having no problems with display when booted into it so I am pretty sure its not a hardware problem. Any any feed back with anyone having similar problem or on how to fix would be appreciated.

Here is some info on laptop

This sounds like an nvidia bug:

bug reports: www.nvnews.net/vbulletin/showthread.php?t=46678

Note that nvidia includes a bug generator script in its package, just follow those steps then file bug reports using both beta and current stable drivers, ie, two bug reports.

I haven't seen any real bugs, it's also possible that you have a hardware problem, or that the new xorg is acting up on your toshiba, hard to say, but nothing we can do here as far as I know, file the bug reports is my advice with nvidia, it's fast and easy to do.

Also, give the 173.xxxx driver a try as well, that usually works with later hardware.

Thanks for the link TA.

I'll have a poke around it and see if anyone else was experiencing the same symptom on their forum. For all purposes it does work OK its just Logging out or dropping to console so its liveable as almost all time is spent in X anyway.

Just as a curiosity used smxi to install the standard Xorg nv driver but it gave me a black screen when choosing to start desktop after driver install. rebooting only dropped me into text log-on so used smxi to reinstall nVidia beta driver again ... only seems to work with the 3d drivers, have not tried the 173... driver I will try it just to see. Starting to wonder if Toshiba doesn't makes some hardware tweaks of their own that they don't tell us.. then again like you said could be the new Xorg.

I always wince when I see someone post a bug report with a Toshiba, it's not as well supported in some areas.

However, the type of issue you are reporting is probably exactly what the nvnews/nvidia guys need to see, it's not a standard case, though it's hardly unusual. I'd file a bug report with beta and standard drivers, read their bug how to and file all required information for each driver, it's pretty easy to do, and should only take you about 15 or 20 minutes. Note especially they want to see the actual xorg event, ie, generate the bug after you enter init 3 from kde, not before, then assemble the files and attach them on their forums.

nvidia does a really good job making filing bug reports painfree, it's one of the only groups I'll file bug reports, for,. my experience with my linux kernel bug certainly convinced me not to waste my time with the kernel guys again....
