Bug 453368 – x11-base/xorg-server-1.13.1 - Jumpy touch after --map-to-output

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Matthew Schultz 2013-01-21 16:17:31 UTC]

If you have a touch screen as a second monitor and you call:

xinput --map-to-output 9 VGA1 (assuming VGA1 is your touchscreen and 9 is the id of touchscreen input id listed in xinput),

then when you attempt to touch the touchscreen the pointer moves to the right position but then jumps after you let go and does not accomplish the intended action.  There is an upstream patch for this that applies cleanly to 1.13.1 that I will upload here.

Reproducible: Always

Tested and applies cleanly to 1.13.1.

[Comment 3 Matthew Schultz 2013-01-21 16:22:34 UTC]

Note that since this was fixed upstream, this patch would not need to be applied to 1.14 when it comes out.  Upstream has also indicated that this patch may be backported to 1.13 but with no definitive time in which that might happen.

You can unmask xorg-server-1.13.99.901 to get this fix.

[Comment 5 Matthew Schultz 2013-01-21 17:16:26 UTC]

I would but unfortunately the latest nvidia-drivers as well as xf86-video-virtualbox prevents me from doing so at the moment.

[Comment 6 Chí-Thanh Christopher Nguyễn 2013-01-24 18:14:38 UTC]

Anyway I will mark this as fixed, since 1.13.99.901 is in tree and contains this patch. If the fix is simple enough, it will probably show up in 1.13 branch at some point.
