Hi,
I am new to linux (coming from macos). I am using a T490 thinkpad and I am running the XFCE version.
Everything is working fine when I am using resolution 1920x1080. But whenever I change the resolution to anything else the screen is not filled — there are black stripes to the sides.
xrandr
returns
Screen 0: minimum 8 x 8, current 1280 x 1024, maximum 32767 x 32767 eDP1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 310mm x 170mm panning 1280x1024+0+0 1920x1080 60.01 + 59.93 1680x1050 59.95 59.88 1400x1050 59.98 1600x900 60.00 59.95 59.82 1280x1024 60.02* 1400x900 59.96 59.88 1280x960 60.00 1368x768 60.00 59.88 59.85 1280x800 59.81 59.91 1280x720 59.86 60.00 59.74 1024x768 60.00 1024x576 60.00 59.90 59.82 960x540 60.00 59.63 59.82 800x600 60.32 56.25 864x486 60.00 59.92 59.57 640x480 59.94 720x405 59.51 60.00 58.99 640x360 59.84 59.32 60.00 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis)
I tried to follow solutions I have seen online such as setting the underscan off, but my xrandr utility does not have the “underscan” option. Specifically, when I run
xrandr --output eDP1 --mode 1280x1024 --set underscan off
it returns
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputProperty)
Serial number of failed request: 39
Current serial number in output stream: 39
Any help will be greatly appreciated.
Thanks.
