我刚刚买了一个LG 25UM58超宽显示器,并设置它与Windows工作(Ubuntu20.04双启动)。但是,在Ubuntu中,当我尝试使用以下过程添加模式时:
$ cvt 2560 1080 50
# 2560x1080 49.95 Hz (CVT) hsync: 55.65 kHz; pclk: 188.75 MHz
Modeline "2560x1080_50.00" 188.75 2560 2712 2976 3392 1080 1083 1093 1114 -hsync +vsync
$ xrandr --newmode "2560x1080_50.00" 188.75 2560 2712 2976 3392 1080 1083 1093 1114 -hsync +vsync
$ xrandr --addmode DP-0 2560x1080_50.00
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 37
Current serial number in output stream: 38
我的GPU是Nvidia Quadro K420,具有1 DP (超宽监视器)和1 DVI (正常监视器)。我尝试过不同的方法(甚至使用新的驱动程序,这会导致DVI屏幕和DP屏幕分辨率的混乱),但是错误仍然存在。
更新:根据codlord的建议,这是我运行lshw -c video
时的结果:

另外,xrandr

我会在运行xrandr
和lshw -c video
的结果上面编辑您的问题,这样人们就可以看到您的设置的更多细节。
我有两个这样的LG超宽(不确定的确切型号)在一台PC上,但从来没有任何问题与Ubuntu (我个人不使用任何专有驱动),他们只是检测和工作,没有任何自定义设置。
我不知道我的输出是否会帮助您确定添加自定义模式的兼容设置?

我不得不安装驱动程序。"Windows“键->类型”驱动程序“,并选择”其他驱动程序“。然后选择一个上面写着“测试”(链接中的截图)。那就重新开始。
