** Description changed: Binary package hint: xserver-xorg-video-intel The displayed screen on my monitor is typically shifted down by some 16pixels : e.g. on the desktop the bottom panel disappears by about half, and a black area of the same height appears at the top of the screen. This appears to be related to the intel video graphic, as the picture is unstable on two computers each using intel graphic and running different versions of ubuntu, while the picture is rockstable for days when the same monitor is used on computers with Nvidia card or AMD onboard graphic . The monitor is an IBM 14" (type 9514-B23) flat screen with native resolution of 1024x768. One of the problematic computers has the motherboard Intel D945GCLF2 (w. atom330). It is booted with either Karmic (default install) or Lucid (default install) as well as an install with the latest DRM as suggested by #13 in Bug #372575 (using https://edge.launchpad.net/~apw/+archive/red ). The other computer is a netbook Acer Aspire One 110L, running karmic (default install). The picture can be restored by switching the monitor off and on. It jumps back to the shifted screen after a time period ranging from 1 second to several minutes. It tends (but is not always so) to jump sooner when a faster refresh rate is selected ( 75Hz faster than 70Hz, faster than 60Hz). The monitor provides info about the video signal by its OSD; it says: @1024x768 and 75Hz H-Frequency: 60.18 kHz C-Frequency 75.23 Hz Sync Polarity H:+ V:+ The signal is the same before and after the jump. This identical signal is reported when the nvidia card is connected, but I never observed the jump with the nividia card. + + [lspci] + 00:00.0 Host bridge [0600]: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub [8086:2770] (rev 02) + Subsystem: Intel Corporation Device [8086:464c] + 00:02.0 VGA compatible controller [0300]: Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2772] (rev 02) + Subsystem: Intel Corporation Device [8086:464c]
