我有一台装有 Ubuntu 22.04 的 Dell i7 iRis xe Graphics 笔记本电脑，我无法在外接显示器上设置高于 1920x1080 的分辨率
除了使用 chatgpt 看看是否可以给我提供替代方案外，我还搜索了整个论坛，但我无法解决我的问题。
我有一台技嘉显示器，其分辨率最高可达 2560 像素 x 1440 像素，频率最高可达 165 Hz。分辨率类型 QHD
我有一台与这款非常相似的笔记本电脑，是戴尔 Inspirion i5 iRIS xe，我把它放在技嘉显示器上，2560x1440 的分辨率很好，它甚至还给我提供了 3440x1440 的选项
我试过：
Install ubuntu 22.10 update kernel.
Install ubuntu 20.04 update kernel, update it to 22.04.
Install ubuntu 22.04 upgrade kernel
Install graphics manually
上述选项对我都不起作用。
尝试以下
cvt 2560 1440 60
cvt --reduced 2560 1440 60
cvt 2560 1440 33
我也无法使其中一些分辨率生效，唯一一次产生效果并导致我的显示器黑屏并出现信号超出范围之类的消息是在使用 ubuntu 20.04 时使用以下命令：
xrandr --newmode "2560x1440_33.00" 162.75 2560 2696 2960 3360 1440 1443 1448 1470 -hsync +vsync
xrandr --addmode HDMI-1 2560x1440_33.00
xrandr --output HDMI-1 --mode 2560x1440_33.00
在 ubuntu 22.04 中，我在 xrandr 中有以下内容

然后我放
xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
然后
xrandr --addmode XWAYLAND1 2560x1440_60.00
I also tried with
xrandr --addmode XWAYLAND1 "2560x1440_60.00"
最后
xrandr --output XWAYLAND1 --mode 2560x1440_60.00

Looks like i2c was successful. Have a good day.

正如我之前提到的，我已经降低了频率，并进行了更多测试，我不知道我的笔记本无法检测到的问题是显示器分辨率。
附言：我不想更换操作系统，我一生都使用 Ubuntu 进行编程，并且我的所有生产环境都使用 Ubuntu Server
