Public bug reported:
[Impact]
The delay phenomenon is serious in 'External display mode' during the
'On-demand' mode working.
Please reference lp:1940247 and lp:1919118.
[Fix]
I installed 21.10 on Raptor12(ThinkPad-P15-Gen-2i), with xorg-server
2:1.20.13-1ubuntu1 and nvidia-495.38 test driver, this issue is solved. But in
20.04, it's still 2:1.20.11-1ubuntu1~20.04.2.
[Test]
On Raptor12(ThinkPad-P15-Gen-2i), P17 Gen 2 and P1 Gen 4, with latest 20.04, it
could be reproduced.
[Where problems could occur]
Although the nvidia driver is not released, I thought it's no harm to upgrade
xorg-server first.
