@tonypanduru I'd like to share a slightly improved workaround on this for those still dealing with the issue. The core problem seems to be that the mouse cursor can go into a negative X position by one pixel when moved to the far left of the screen. With either the now obsolete intel proprietary driver or the current intel modesetting driver, this causes issues (exact symptoms are different for each, but seem to be from the same root cause).
My previous workaround got by this by scaling the entire desktop to 99.99% of its former size. This prevented the cursor from getting to the -1 X position, but came at a cost of lost performance and some screen tearing in videos and games. This was due to a bilinear filter being applied by xrandr to the whole desktop to accommodate the slight re- size. The following command avoids this issue and instead merely shifts the entire desktop right one pixel. It still works around the issue, but seems to avoid the overhead of resizing the whole desktop (which preserves display integrity and performance). xrandr --output HDMI-3 --transform 1,0,-1,0,1,0,0,0,1 It would be nice to get a root cause fix for this, but this workaround seems to do the trick with very little downside. As before, replace the "HDMI-3" with the name of your active display (found by running xrandr with no options) and place the command in your ~/.xprofile (or make a startup app entry in your desktop manager). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1767654 Title: [Intel Braswell] Cursor gets stuck on left side of the screen Status in Linux: New Status in gnome-shell package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in mesa package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: When moving the cursor to the left side of the screen, it stops close to the edge. The cursor still moves over in the area but invisible until I move it out of the area. When it doesn't do this, glitching occurs on the screen where the cursor is until I log out. And on screen cast it shows the cursor going to the side of the screen and moving.
