해상도를 설정하려고 할 때 "감마 크기를 가져오지 못했습니다" 오류

해상도를 설정하려고 할 때 "감마 크기를 가져오지 못했습니다" 오류

11.10에서 허용되는 최대 해상도는 1024x768이고 모니터는 Windows에서 1280x800을 지원합니다.

xrandr을 통해 이 문제를 해결하는 방법을 본 적이 있지만 감마 크기를 가져오는 데 실패했다는 메시지가 항상 표시됩니다.

 xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768       61.0* 
   800x600        61.0  
   640x480        60.0  

내 노트북에 1280x800 해상도를 추가할 수 있는 다른 방법이 있나요? 해결 방법이 있나요?

미리 감사드립니다.

답변1

Xorg.conf 파일에 모델라인을 추가해야 합니다. 다음 내용을 읽어주세요: http://www.x.org/wiki/FAQVideoModes Windows가 올바른 해상도로 실행되고 있으므로 멀티탭에 관한 부분이 흥미로울 수 있습니다.

답변2

xrandr에 표시된 최대 해상도가 1024x768로 제한되어 있음을 확인했습니다. 어쩌면 먼저 아래 위키를 따라 X가 비디오 RAM을 인식하도록 강제할 수도 있습니다.

인식되지 않는 비디오 카드

즉, /usr/share/X11/xorg.conf.d/99-vesahack.

재부팅 후 최대값이 성공적으로 변경되면 --newmode--addmode등 의 다음 단계를 진행할 수 있습니다.

Ivy Bridge를 디버깅하는 동안 우연히 이 문제가 발생했습니다. 이것이 "감마 크기를 가져오지 못했습니다" 오류의 원인일 수 있다고 생각합니다.

/etc/X11/xorg.conf를 백업하고 아래 줄을 추가하세요. OEL6.5에서 저에게 효과적이었습니다.
