我正在尝试将 10 英寸触摸屏(原始分辨率:1280x800)切换到 1024x768,但我尝试的所有操作都被忽略或导致错误。据报道,显示器支持分辨率,但xrandr --verbose
报告(我使用的是默认的 VESA 驱动程序):
xrandr: Failed to get size of gamma for output default

如果我尝试通过更改分辨率xrandr --output default --mode 1027x768
,我会得到:
xrandr: Failed to get size of gamma for output default
xrandr: Configure crtc 0 failed
据我所知,只有第二行与我的问题有关;我不知道为什么xrandr
要配置crtc 0
,但我只连接了触摸屏。
失败了,我尝试直接使用以下配置模式xorg.conf
:
Section "InputClass"
Identifier "calibration"
MatchProduct "DIALOGUE INC PenMount USB"
Option "Calibration" "95 911 93 919"
Option "SwapAxes" "0"
EndSection
Section "Monitor"

Monitor "disp0"
SubSection "Display"
Modes "1024x768_60.00" "1024x768"
EndSubSection
EndSection
不幸的是,这不起作用,要么Xorg.log
显示以下内容:
[634043.694] (II) VESA(0): Not using mode "1024x768_60.00" (no mode of this name)
[634043.694] (II) VESA(0): Not using built-in mode "1024x768" (no mode of this name)
为什么这不起作用?还有什么我可以尝试让显示器切换到 1024x768?
