我的图形似乎有点滞后。我输入了命令:
dmesg | egrep 'drm|radeon'
我收到了这条消息
[2.205753] [drm] Initialized drm 1.1.0 20060810
[2.246056] [drm] VGACON disable radeon kernel modesetting.

[2.247842] [drm] Initialized radeon 1.34.0 20080528 for 0000:01:05.0 on mino
我的问题是,这些行是什么意思:
[2.246866] [drm] No driver support for vblank timestamp query.
[2.247840] [drm] No driver support for vblank timestamp query.
是什么意思?我是新手,只是想知道这是否值得担心,我在 Google 上找不到任何东西。
