[CLOSED]VGA 黑屏

台式机一直用双屏,A卡radeon系列,插一台vga显示器和一台hmdi显示器,前天重启,发现vga显示屏黑屏了……(hmdi正常), 经过测试(只插一台显示器)发现VGA口在grub阶段可以显示,但是随后进直接进入黑屏,这是怎么回事哈……
1:只插vga,则grub可见,OS启动进程就黑屏
2:插vga+hmdi,则vga黑屏
3:换用live os ,现象一样

Re: [CLOSED]VGA 黑屏

今天拿了张新的Novall Quadro 600 卡测试,问题解决
不过在中间还是学习了不少知识,
因为我的两个显示器分辨率分别是1920X1080   和1024X768,所以如果同时插着两个显示器,启动的话,X不能自行处理,显示器会报超频(估计),所以只能插1920X1080分辨率的启动,然后在用xrandr点亮第二个显示器。

Re: [CLOSED]VGA 黑屏

你自己写conf 啊,如果xrandr能亮第二个屏那为啥不能写成conf
