Good afternoon my fellow Manjaro Linux users i need some help with adding 1280 X 1050 resolution to my Lenovo ThinkPad T500 system yes i know its a older computer but i love Thinkpads and this one is decently fast i would like to add the resolution permanently can anyone show me step by step using xrandr here is my output thanks in advance

to add a missing or custom display resolution, you need to calculate the VESA Coordinated Video Timing (CVT) modes for it. you can do this using the cvt utility. Example for a 1280x1050 resolution:

cvt 1280 1050

next, copy the Modeline ("1280x1050_60.00" 111.75 1280 1368 1496 1712 1050 1053 1063 1089 -hsync +vsync) from the output of the cvt command and use it to create a new mode using the xrandr:

xrandr --newmode "1280x1050_60.00"  111.75  1280 1368 1496 1712  1050 1053 1063 1089 -hsync +vsync

(modeline maybe different for you)

xrandr --addmode XWAYLAND0 1280x1050_60.00

now set different resolution:

xrandr --output XWAYLAND0 --mode 1280x1050_60.00

the above changes are only temporary and work for the current session. to make them permanent add these lines in your /etc/X11/xorg.conf.d/10-monitor.conf file:

Section "Monitor"
    Identifier "XWAYLAND0"
    Modeline "1280x1050_60.00"  111.75  1280 1368 1496 1712  1050 1053 1063 1089 -hsync +vsync
    Option "PreferredMode" "1280x1050_60.00"
EndSection

Section "Screen"
    Identifier "Screen0"
    Monitor "XWAYLAND0"
    DefaultDepth 24
    SubSection "Display"
        Modes "1280x1050_60.00"
    EndSubSection
EndSection

Section "Device"
    Identifier "Device0"
    Driver "intel"
EndSection

when i did that step i got this error

xrandr --newmode “1280x1050_60.00” 111.75 1280 1368 1496 1712 1050 1053 1063 1089 -hsync +vsync

maybe you can skip this step because that mode is already there. go from here:

ok i skipped that step then did this xrandr --addmode XWAYLAND0 1280x1050_60.00 got the green check did the xrandr – output XWAYLAND0 --mode 1280x1050_60.00 and got this error

xrandr --output XWAYLAND0 --mode 1280x1050_60.00  :heavy_check_mark:

see if this helps :point_down:

You maybe want to use -r for cvt if used with modern LCDs as mentioned to this answer: https://askubuntu.com/a/19956
So cvt -r 1280 1050 in this case.
