[CLOSED]VGA 黑屏

lijing48301243 · 2019-03-21 11:55:19

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

测试了老毛桃系统，估计显卡问题

驿窗 · 2019-03-21 17:42:33

显卡坏了？

lijing48301243 · 2019-03-22 12:34:33

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。

你自己写conf 啊，如果xrandr能亮第二个屏那为啥不能写成conf
