As requested by @penalvch, tested exact same hardware (nta3500 computer, hp vs19e display) with today's daily live image downloaded from at http://cdimage.ubuntu.com/daily-live/current/xenial-desktop-amd64.iso displayed as "xenial-desktop-amd64.iso 04-Mar-2016 08:29 1.5G" with md5sum 497d36d2b35c8db1c246af281acb36cc and sha1sum e036ed8aa1deedbbbc32bf5b8df0f01ac23e8286
Result: native resolution is correctly automatically detected and selected, no need for any manual workaround (no need for xrandr). So, this bug does not affect 16.04 daily live on this hardware combination. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1307176 Title: Resolution limited to 1024x768 Status in xserver-xorg-video-ati package in Ubuntu: Incomplete Bug description: Bug reported with xdiagnose. # Summary On installing Ubuntu 13.10 or 14.04 on a NTA3500 nettop with a VGA monitor HP vs19e (native resolution 1280x1024), a resolution of 1024x768 is obtained. The bug is not that the correct resolution cannot be obtained at all (there's a workaround below with xrandr) but about the fact that is is not automatically selected despite good EDID data available from monitor. # Details Machine has two video output ports: HDMI and DVI. No monitor is plugged on HDMI. Monitor used is plugged on DVI with a DVI-to-VGA passive adapter. The open-source driver is used. xrandr and graphical tools don't offer more than 1024x768 on this screen. xrandr output: Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 DVI-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 376mm x 301mm 1280x1024 60.0 + 75.0 1152x864 75.0 1024x768 75.1 70.1 60.0* 832x624 74.6 800x600 72.2 75.0 60.3 640x480 75.0 72.8 60.0 720x400 70.1 HDMI-0 disconnected (normal left inverted right x axis y axis) VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 # EDID information sudo get-edid | parse-edid This is read-edid version 3.0.1.

Have a good day. # Additional information, comparison Same monitor was used on various machines, bug only happens on this machine. With no change to hardware, when using ATI proprietary driver, 1280x1024 is available by default (no need for a workaround). # Workaround A similar problem was reported on http://askubuntu.com/questions/207716/ubuntu-12-10-resolution-stuck- at-1024x768-using-open-source-radeon-driver .

How to diagnose the reason why the correct resolution as reported by the monitor is not used by open-source driver ?
