There appears to be a bug in the evdev driver though. If moving the cursor in the X-axis only, or in the Y-axis only it works fine. If I move the cursor in the X & Y axis at the same time (eg bottom-left -> top-right of screen), the position of the cursor on screen seems to 'loose' the X co-ordinate updates until I finish moving the mouse. eg, move from bottom-left -> top-right of screen, while the mouse it moving the cursor will only update the Y co-ordinate. When I stop moving the mouse, it finally updates the X co-ordinate Version-Release number of selected component (if applicable): xorg-x11-drv-evdev-1.1.2-3.fc7 How reproducible: Always Steps to Reproduce: 1. Boot a Fedora 7 paravirt Xen guest 2. Configure it to use attached Xorg config file 3. Start X 4. Move mouse at a medium speed from bottom-left to top-right corner of screen Actual results: Mouse moves up left-hand side of screen, and then at last movement flips over to top-right corner Expected results: Mouse moves smoothly diagonally across the screen from bottom-left to top-right.

This seems to be causing the X axis update to be lost - resulting in the cursor travelling up the left-hand side of the screen when moved diagonally. This manual sync looks unneccessary since the kernel sends an explicit sync event whenever one ie needed. So I wrote the attached patch which removed the two redundant calls to sync pointer position. This resulted in smooth mouse movement expected. I'm a little puzzelled why these explicit sync calls are in the driver at all - not clear they could ever have worked correctly ?!?!

This updated patch includes a fix to also remove use of SendCoreEvents/DontSendCoreEvents flags which allows the driver to be rebuilt with the pointer sync fix.

Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Reply at: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/92354/comments/7 ------------------------------------------------------------------------ On 2008-06-17T01:33:58+00:00 Bug wrote: Fedora 7 changed to end-of-life (EOL) status on June 13, 2008.
