Old title - "change resolution to 1280x1024 using xrandr gives: X Error of failed request: BadValue (integer parameter out of range for operation)"
I have installed a fresh Ubuntu 17.10 and have a monitor with 5:4 resolution. settings has no resolution higher than 1024x768. But I need the resolution 1280x1024 (5:4). I use the default motherboard graphics card:
# lspci|grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)
Also xrandr gives the following:
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
XWAYLAND0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 59.92*+
I tried to add the 1280x1024 resolution using xrandr. so first created the resolution information using gtf:
$ gtf 1280 1024 60
# 1280x1024 @ 60.00 Hz (GTF) hsync: 63.60 kHz; pclk: 108.88 MHz
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync
Then added to resolutions:
xrandr --newmode "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync
then again did the command: xrandr --addmode XWAYLAND0 1280x1024_60.00
Then nothing changed. When I tried to change it using xrandr --output XWAYLAND0 --mode 1280x1024_60.00 --rate 60
But an error occurred:
$ xrandr --output XWAYLAND0 --mode 1280x1024 --rate 60
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 7 (RRSetScreenSize)
Value in failed request: 0x0
Serial number of failed request: 21
Current serial number in output stream: 22
I don't know what did I do wrong. Or how to change resolution to the correct one: 1280x1024
