[ Impact ]
Input or the entire screen may freeze at times on systems using the
Nvidia Xorg driver with GNOME.
[ Test Plan ]
0. Set up a desktop with Nvidia driver 545 or 550.
1. Log into Ubuntu, ensuring it's a Xorg session.
2. Open a Terminal, resize it vigorously, and type several lines of text.
3. Verify that input never froze for any perceptible period of time.
4. Run: journalctl -b0 | grep MetaSyncRing
5. Verify the above command does NOT show messages such as:
Window manager warning: MetaSyncRing: Sync object is not ready -- were events handled properly?
Window manager warning: MetaSyncRing: Sync object is not ready -- were events handled properly?
Window manager warning: MetaSyncRing: Sync object is not ready -- were events handled properly?
Window manager warning: MetaSyncRing: Too many reboots -- disabling
[ Where problems could occur ]
Anywhere in Nvidia (proprietary driver) Xorg sessions since that's the
code being modified.
[ Original Description ]
There is a noticeable delay in input while using the native terminal. I
belive it was caused by a recent software update, as this issue is
relatively new.
