Xorg & Samsung SyncMaster 245B

["Jon Nicholson" <jonoton@gmail.com>]

I've just upgraded to lenny on my Dell Latitude D430, after a bit of tinkering most things are working fine. However I've still got a small problem with X. I'm using an external monitor, a Samsung SyncMaster 245B, 24" screen capable of 1920x1200 resolution.

I had this working fine under etch but with the upgrade the screen is being driven slightly wrong, the monitor reports a resolution of 1920x1203. This causes bluring and missing lines on the screen.

I've frigged with the modelines in the config, but none of the ones that I can find seem to fix the problem, could anyone point me in the right direction?

Here's the relevant section of the xorg.conf:-

Section "Monitor"
  DisplaySize  519 322
  HorizSync    30-81
  Identifier   "ExternalLCD"
  ModelName    "SyncMaster 245B"
  Option       "DPMS"
  VendorName   "Samsung"
  VertRefresh  60-75
  Modeline     "1920x1200" 154.00 1920 1968 2000 2080 1200 1203 1209 1235
#  Modeline "1920x1200" 168.86 1920 1950 2592 2624 1200 1225 1235 126
  Option       "DPI" "96x96"
EndSection


(the commented out modeline doesn't work any better)


Any help appreciated,
