英特尔模式驱动程序屏幕撕裂

Question

当XORG使用Intel模式驱动时，我正面临撕裂问题。还有其他人面临这个问题吗？如果有人有解决办法，请帮帮我。

我也试过英特尔的司机

/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "TearFree" "true"
EndSection 

但最终还是出了车祸。

Answer 1

英特尔Xorg驱动程序长期以来一直被废弃，不建议使用，对于适当的模式设置驱动程序，您应该使用以下配置：

Section "Device"
    Identifier "modesetting"
    Driver "modesetting"
    Option "TearFree" "True"
EndSection

虽然我不确定这个特性是否已经发布到了正式的Xorg版本中。更多信息在这里：https://www.mupuf.org/blog/2018/09/24/teaching_X_模态调整_新的_伎俩/
