請提供
1. Ubuntu 版本 及 登入桌面
2. 顯卡詳細品牌與型號
3. Monitor 詳細品牌與型號
4. 把下面指令 複製 貼進終端機 執行
4-0. sudo apt install hwinfo
4-1. sudo hwinfo --framebuffer
4-2. xrandr -q
4-3. sudo cat /etc/default/grub | grep GRUB_GFXMODE
4-4. sudo cat /etc/default/grub | grep GRUB_GFXPAYLOAD_LINUX
4-5. sudo lshw -numeric -class video
4-6. xrandr --verbose | grep -A8 EDID
4-7. echo $DESKTOP_SESSION
把 4-1 ~ 4-7 結果直接 選取/複製 貼上來
