如果先开了电脑，过会在开电视，就出不来X window了
CPU是I3，带GPU的，系统是Arch，驱动应该是Intel i950
dmesg最后显示：

cat /sys/class/drm/card0-HDMI-A-2/status
connected
电视右下角显示1024x768,不知为何不是1080 |

莫非我需要写个钩子脚本，调用xrandr? |

发帖数: 9013 | 5 郁闷了，我在UDEV的Hook里调用xrandr, 发现xrander返回：can't open display
cat monitor-hotplug.rules
KERNEL=="card0", RUN+="/myconfigs/hotplug_tv.sh"
cat hotplug_tv.sh
#!/bin/bash
d=`date`
log=/myconfigs/a.log
echo "$d: TV connected" > $log
sleep 20
/usr/bin/xrandr --output HDMI2 --mode 1920x1080
/usr/bin/xrandr >> $log
echo "xrandr output $?" >> $log |
