我正在运行 Ubuntu 21.04，尝试按照此链接中的说明进行操作
我执行以下操作：
cvt 5120 1440 -r
sudo xrandr --newmode "5120x1440R" 469.00 5120 5168 5200 5280 1440 1443 1453 1481 +hsync -vsync
xrandr | grep -e " connected [^(]" | sed -e "s/\([A-Z0-9]\+\) connected.*/\1/"
上述回报
XWAYLAND0
XWAYLAND4
所以我
sudo xrandr --addmode XWAYLAND4 5120x1440R
然后尝试选择它
xrandr --output XWAYLAND4 --mode 5120x1440R
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 139 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Value in failed request: 0x780
Serial number of failed request: 29
Current serial number in output stream: 29
有人知道如何解决这个问题吗？
谢谢你的帮助，凯文

Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
256-byte EDID successfully retrieved from i2c bus 3
Looks like i2c was successful. Have a good day.
You seem to have too many extension blocks. Will not continue to parse

不幸的是，分辨率受到 GPU 的限制。CometLake-U GT2 [UHD Graphics] 是一款集成 GPU。
Max Resolution (HDMI)‡ 4096 x 2304@24Hz Max Resolution (DP)‡ 4096 x 2304@60Hz Max Resolution (eDP - Integrated Flat Panel)‡ 4096 x 2304@60Hz
您需要一个支持这种分辨率的独立图形适配器。
