I installed SLES 11.2 on a Dell Latitude laptop and the display is off center. Approx 7% of the right side is cut and showing on the left side. I can slide mouse all the way to the right and the cursor pops over to the left and continues like it’s in dual display mode. This problem doesn’t happen in failsafe mode however the screen is stretched.
The graphics card is on-board Intel Ivybridge M GT2. The installer chose the monitor as “LGD 3HT47 140WH4 LCD” and set the resolution to 1366x768 WXGA (it’s a 14" display). I’ve tried several different resolutions and monitor types including Dell but can’t get it working.

When you’re at the grub menu, try adding the parameter “nomodeset” and
see if that helps.
Generally, though, I’d either look at putting SLED on a laptop, or
openSUSE.
The expected resolution is 1366x768. Here’s the output from xrandr.

I recall reading about users experiencing this ‘display offset’ issue with certain graphics hardware and kernel driver regressions some time back. Can you tell us which chipset and driver you’re using?
/sbin/lspci -nnk
IIRC, there was an intel bug whereby “1366x768” was an issue with some intel hardware, (and if I’m not mistaken, had something to do with 1366 not being divisible by 8)… but it was some time ago. Anyway, here’s an openSUSE bug report that may be relevant to your situation
This linux mint thread reports the same issue (same Intel graphics chipset).
They also mention
[QUOTE]Editing /etc/modprobe.d/i915-kms.conf and changing modeset=1 to modeset=0 and rebooting fixes this issue, and then the console, followed by the display-manager shows properly (centered) on the screen. But the virtual consoles are gone!! Meaning, if I try to switch to consoles with Shift+F# keys (1 to 6), I am stuck at a greyish background, kind of like the color of the background of the display-manager (mdm in the case of LMDE).
For that, I had to upgrade to liquorix kernel 3.4.0-10, and the wrong x-offsetting issue with the i915 module loaded was resolved, and I no longer had to disable modeset.[/QUOTE]
So, this is really a kernel issue, and it appears it’s been fixed with a later kernel. Maybe one of the updates or service packs fixed it perhaps? However, I’m not familiar with SLED/SLES products, and the possibility of upgrading kernels with them. A bug report should be submitted IMHO.
