[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
Ok, based on this latest information I'm going to mark this bug as invalid because the patch added as part of the SRU should be making things more correct, and the difference appears to be handled appropriately by modifying the acceleration scheme parameters. I will also note that the acceleration and sensitivity is greatly affected by the precision of the mouse, and that the X input handling is not automatically scaled to take this into account. For example, the default acceleration and sensitivity is too high on a high precision mouse like the Apple Magic Mouse, while it is perfectly reasonable for other mice. Please feel free to reopen the bug report if you believe this is not the appropriate outcome.

[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
No nothing wrong...Its just different as the pointer have this acceleration issue. I tried reducing the acceleration. By default the xinput feedback for the mouse is: accelNum is 2 accelDenom is 1 threshold is 4 I reduced acceleration, now the output is: accelNum is 1 accelDenom is 1 threshold is 4 Reducing acceleration by just one point helped as pointer behavior is now better. But when I increase it back to 2-1-4, it again starts to feel same as before. Also, I don't know if 1-1-4 feels better just because I reduced the acceleration or the problem is really solved. Its really hard to closely observe the pointer for any change in behavior as it just feels if something is wrong or not. But yes, 1-1-4 feels alot better than 2-1-4 anytime on xorg from SRU. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791596 Title: Odd Pointer Behavior After Recent Xserver SRU in Natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
I'm now a bit confused as to what the actual problem you're seeing is. Is it: *) Erratic mouse behaviour: +) pointer moving when not moving the mouse? +) pointer moving in an incorrect direction when moving the mouse? +) pointer not moving at a constant rate when moving the mouse at a constant speed? +) Something else? *) Altered mouse sensitivity: +) Higher sensitivity - pointer moves in the direction expected, but moves further than expected +) Altered acceleration behaviour - pointer takes longer/shorter to get to “full speed” when moving the mouse? Are there any other changes when switching between the xserver-xorg-core versions? Do you have two monitors connected? In any case, as far as I can tell the codepath the patch changes will only be hit by a driver sending an absolute pointer event, which as far as I can tell none of your devices (and certainly not your mouse) will do. So I remain a bit perplexed! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791596 Title: Odd Pointer Behavior After Recent Xserver SRU in Natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
Sorry for creating this confusion as I was unable to describe the issue properly. I should have been to the point. This is what I have been experiencing: *) Altered mouse sensitivity: +) Altered acceleration behaviour - pointer takes *longer/shorter* to get to “full speed” when moving the mouse (This is the exact thing which is happening.) No there are not any other changes and no multi monitors setup. I have recorded the device.prop and device.record files yesterday when I suddenly started facing the problem. I will upload them here. As much as I want to know what is the problem, I hate wasting time and efforts of developers. If this problem is not reproduced or cannot be further investigated, please go ahead and maybe we can see later if some other users experience the same problems or similar bugs are reported. Also if some further testing is required I will do it. ** Attachment added: device.prop https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/791596/+attachment/2156602/+files/device.prop -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791596 Title: Odd Pointer Behavior After Recent Xserver SRU in Natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
Ahhh! Thanks Chris and dart for clearly stating that it's the acceleration that's wrong. This code path may interfere with the acceleration, but I would guess that if anything this patch would restore acceleration to what it should be. dart, does the new xorg-server feel wrong, or just different than the previous version? Would increasing/decreasing the acceleration in the mouse preferences resolve the issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791596 Title: Odd Pointer Behavior After Recent Xserver SRU in Natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
Chris, I installed xorg from your PPA. The first time I tested, I did not notice any difference in PPA version and SRU version. But then another time, when using natty-updates, the mouse sensitivity increased greatly. So I installed PPA version and the sensitivity came back to normal. This is really really confusing and random. Now I am totally lost between these three versions of xorg trying them again and again. Is there a way to measure mouse sensitivity and other input info from command line or some other tool? I used 'xinput get-feedbacks' command to get some info but it shows same output in all three versions of xorg.

Chase, This -- or that at the time you did *not* see the bug in either the PPA or the SRU versions? I tried once again. From the stock xorg version, I upgraded to Xorg SRU. The sensitivity increased. Then I installed PPA version, sensitivity came back to normal. Why this has not happened the very first time and why this has happened this time and earlier, I have no clue. Its seems to be random. Not sure how can I help. Can't we record exact mouse sensitivity in numbers? Also, I have gone crazy in observing pointer behavior again and again in different xorg versions. Right now I use the stock xorg version without any problems. Also, I tried different things like changing usb ports, disabling touchpad completely when using usb mouse, different optical mouse and even changing the mouse pad to see if there is some other problem in hardware side, but the sensitivity problem creeps in.

[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
Thank you for that. I've looked at the patch in question (503_fix_masked_transformed_valuators), and it looks plausible that there's a change in behaviour, although I don't see why it would only manifest after a few minutes' uptime. It appears that we should revert that patch pending further investigation. ** Changed in: xorg-server (Ubuntu Natty) Status: New = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791596 Title: Odd Pointer Behavior After Recent Xserver SRU in Natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Could you please check if the Xserver package in https://edge.launchpad.net/~raof/+archive/aubergine fixes the mouse behaviour for you? I've reverted the patch most likely to be the problem in that package.

[Bug 791596] Re: Odd Pointer Behavior After Recent Xserver SRU in Natty
Chase, I followed your instructions. I still get the odd pointer behavior. This is kind of hard for me to explain. With the playback I did not notice any issue. But with the latest updated xorg, the pointer movement always *feels* odd. By feeling I mean that I cannot notice it by just looking at pointer movement on the screen but it always feels erratic and less accurate. Sorry for being ambiguous. Also, it seems this odd behavior is not noticeable in a fresh session but only starts after a few minutes' uptime. I tested this behavior with two different optical mouse and still the same behavior. Can this affect gaming? I play Urban Terror on my system and it is most noticeable there. Moving the player around with mouse in the game feels more erratic than working on the desktop with files etc. All these issues on my system go away as soon as I downgrade to stock xorg version. The odd feeling + mouse movement in the game and on the desktop, everything comes back to normal.

dart, I tried playing back the recording, but it did not appear to have any issues. Can you upgrade back to the latest xorg-server-core package and follow the steps at the end of https://wiki.ubuntu.com/Multitouch/Testing/uTouchEvEmu#Debugging to play back the recording on your computer? If you see the issue with your recording, then there's some difference between our two machines. If you don't see the issue with your recording, then that may mean you are sometimes getting the right data from the device, and sometimes you aren't (batteries dying if it's a wireless mouse?).
