[Bug 621756] [NEW] Monitor Detection Problem in upgrade to 10.04.1
You have been subscribed to a public bug:
Ubunutu upgrade from 9.10 to 10.04.1, new problem with Monitor (was always unknown but did not bring the following error: after booting the monitor displays the message 'not optimum mode' and recommends 1280x1024 @ 60 Hz. Monitor is in 1280x1024, but supposedly at 0 Hz (!?)
It appears that the EDID is in error for this monitor?
Do not notice any problems with display, and so will probably not fool with xorg.conf.
This mail ends with the listing from get-edid (rather long), Xorg.0.log attached. TIA. Ch.Keller
Background Info:
In menu.lst there is xforcesvesa and vga=795 (this is supported by graphic card, hwinfo confirms this).
