[Bug 1272624] Re: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7
Christopher M. Penalver, in the live USB of 12.04.0 the two-finger scrolling can not be activated under Settings--Mouse. The problem was not reproducable but I put that down to the OS not recognising the second finger. Edward-douse, I tried the newest version of ElementaryOS and the results were similar to 12.04.0 above -- i.e., the mouse worked fine but not with two-finger scroll. Under settings--mouse, there was an option to activate two-finger scroll but this didn't seem to do anything (i.e., scroll was still not being detected when tested in Midori and terminal apps). From these tests alone, there doesn't seem to be a regression as the touchpad driver (which allows two-finger scrolling in 14.04) is not activated in either of these OSs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1272624 Title: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1272624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Scott Hosking, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.14-rc3 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Scott, if you get chance, also test ElementaryOS. I have just switched from that to Ubuntu and Ubuntu Gnome 14.04 for testing and my touchpad (Lenovo Z500) is also quite jerky. Or rather I suppose I would describe it as a grainy movement. In ElementaryOS it was fine although it is also jerky in 12.04 which ElementaryOS is based upon. I'm going to try and find out if the Elementary team adding anything else to their distro. Might not help, but if 12.04 is the same..might be worth a shot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1272624 Title: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1272624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1272624] Re: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7
The main problem seems to be when I place a second finger close to my first finger causing the cursor to jump and jerk across the screen (i.e., disappers and reappears in any other part of the screen). I have tried to alter values in synclient to reduce this but I haven't had much luck. I've compared the touchpad sensitivity in Win7 and this doesn't happen there. As for the touchpad area, the very top and very bottom also are not respsonsive in Win7 so this is probably not an issue, just something I picked up on (#7) when searching for clues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1272624 Title: [Dell Latitude E7440] 14.04 Touchpad not as smooth as Win7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1272624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
