我最近刚刚放弃 Windows 并在我的 PC 上安装了 Ubuntu 22.04.3 LTS，但不幸的是我似乎无法设置我想要的分辨率（3440x1440）
这就是我所震撼的：
CPU：第 11 代英特尔® 酷睿™ i5-1135G7 @ 2.40GHz × 8
GPU：英特尔公司 TigerLake-LP GT2 [Iris Xe Graphics]
显示器：HUAWEI MateView GT 34 英寸超宽曲面游戏显示器，165Hz，21:9 WQHD
我尝试做以下事情（我尝试过使用 X11 和 Wayland）：
首先是X11：

640x480 75.00 72.81 66.67 60.00 59.94
720x400 70.08
我尝试执行以下步骤：
robert@robert-Vostro-3400:~$ cvt 3440 1440 60
# 3440x1440 59.94 Hz (CVT) hsync: 89.48 kHz; pclk: 419.50 MHz
Modeline "3440x1440_60.00" 419.50 3440 3696 4064 4688 1440 1443 1453 1493 -hsync +vsync
xrandr --newmode "3440x1440_60.00" 419.50 3440 3696 4064 4688 1440 1443 1453 1493 -hsync +vsync
xrandr --addmode HDMI-1 "3440x1440_60.00"
xrandr --output HDMI-1 --mode "3440x1440_60.00"
但它不起作用！我得到的是这个错误：
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: 16 (RRCreateMode)
Serial number of failed request: 33
Current serial number in output stream: 33
xrandr: Configure crtc 0 failed
然后我看到一些人建议手动添加 --crtc 0 标志（然后我尝试将其更改为 1 和 2），但我得到了同样的错误
然后我尝试切换到 Wayland 并按照指南将其添加为自定义内核属性，因此我执行以下操作：
robert@robert-Vostro-3400:~$ for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done
eDP-1: connected
HDMI-A-1: connected
编辑此行：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=HDMI-A-1:3440x1440@60"
并跑了一个
sudo update-grub
并重新启动但这也不起作用（是的，在 Windows 上它工作得很好，相同的显示器，相同的 HDMI 电缆，相同的端口）
“有趣”的是，当我查看日志以查看是否存在更有意义的错误时，我看到 X 记录了这些可用模式，因此我认为它识别出这些都是合法的解决方案

...etc etc etc
有什么建议吗？我有点想不出来 :(
