Workaround with nvidia driver nvidia-current-updates = 304.43-0ubuntu0.1: Background: The nvidia driver is not able to get the EDID of the display over the long VGA cable ((WW) NVIDIA(GPU-0): Unable to read EDID for display device DFP-2), and defaults to 'EDID for NVIDIA', which allows 640x480 only. I will use 'DP-1' for the display on the long VGA cable. Solution: Force more modes than the default EDID allows by ignoring and overriding its values. * Have in xorg.conf: Section Device [...] Option ModeValidation DP-1: AllowNon60HzDFPModes, NoEdidMaxPClkCheck, NoDFPNativeResolutionCheck, AllowNonEdidModes Option HorizSync DP-1: 27.0-91.0 Option VertRefresh DP-1: 59-61 #Option ModeDebug True EndSection Modes now should be selectable with nvidia-settings. If you need additional modes, define their 'Modeline's in the active Monitor section. Valid modes will be selectable for DP-1. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1098907 Title: nouveau kernel driver fails to detect display attached via long VGA cable Status in “xorg” package in Ubuntu: New Bug description: nouveau kernel driver fails to detect display attached via long (10+ meters) VGA cable (or via KVM device).
