When my monitor has been shut down by the pc (either through Kpowersave or the KDE power option settings), the screen has “shifted” about halfway to the left. In other words, my entire screen has moved to the left so that only the right half is visible on the left half of my monitor. The right half of my monitor then displays the right-most 20-or-so pixels repeated to infinity. Otherwise it works normally and I can even end the session and it “shifts” back in to normal at the login screen. If I turn of the monitor with the monitor power button, this doesn’t happen.
Any ideas? I’ve searched this forum and it sounds unique (unfortunately).
System is 11.1 with AMD Athlon X2 with Nvidia Geforce 6500 video card running the G02 driver from the nvidia repository. 3d is enabled. The monitor is a widescreen LCD ACER running at 1650x1080.
Sounds like the refresh changed. If you have a monitor driver CD, you might try running sax2 and go to Monitor / Utility Disc and inserting the monitor disc and then choosing your specific model from the list.
O.K., finally got sax to see the utility disk and chosen my monitor (ACER X223W).
Unfortunately, the problem persists. I don’t know if it’s related, but ever since I moved to 11.1, the screen goes black for about 1.5 seconds when certain display settings are altered. For instance:
-when the screensaver starts/stops
-when I change window managers
-even when I select a different screensaver in the list (not actually testing it fullscreen, just when I click it in the list to preview it in that tiny window
I’m thinking maybe the Nvidia drivers are a little screwey in 11.1 still. Do you think it could be related to my “screen shifting” problem? I didn’t have any of these issues in 11.0 with all the same hardware.
For anyone who is looking to solve this problem, I can confirm a simple solution that works – and credit to the folks above for tipping me off. Installing OS 12.1 on an IBM ThinkCenter desktop (3 GB RAM), I got the “half screen problem”, which was really the screen was shifted half way to the left, which basically left the system unusable. This did not happen during the initial install boot from CD, but appeared after the install started, as well as eventual (but tricky due to navigational problems) boot from disk.
Solution? Using the physical screen controls on the NEC MultiSync 1740CX, select the self-configuration button. The problem is fixed, and permanently it seems. Didn’t even need to adjust any driver (which would have been sort of difficult to get to). I hope this helps anyone searching for this solution.
