I've installed Ubuntu for the first time a few days ago (20.04.1 LTS). My current concern is that xrandr
/arandr
as well as the gnome-control-center
do not show my second monitor plugged in via HDMI. Below are a few information and a screenshot from my current system:
inxi
:
$ inxi -G
Graphics: Device-1: Intel driver: N/A
Device-2: NVIDIA GP107M [GeForce MX350] driver: nvidia v: 450.80.02
Display: x11 server: X.Org 1.20.8 driver: fbdev,nvidia unloaded: modesetting,nouveau,vesa
resolution: 1920x1080~77Hz
OpenGL: renderer: llvmpipe (LLVM 10.0.0 256 bits) v: 3.3 Mesa 20.0.8
xrandr
:
$ xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 77.00*
I am running Ubuntu on Intel i7-1165G7 and a NVIDIA GeForce MX350 graphics card. On arandr
, the Outputs
tab only contains a single dropdown field with the "default" screen (even though I would have expected a different name, like "eDP-1"). Also, the message
xrandr: Failed to get size of gamma for output default
Is something I haven't seen on my previous Debian installation on an older laptop. Does this have something to do with my problem? Is it possible to somehow enable the HDMI output on my laptop?
