Patch from Bugzilla report. ** Description changed:
- Binary package hint: utouch - - I recently bought a Dell ST2220T Monitor. On first install, The touch - worked pretty well. But it started to behave weird after restarts. The - behaviour is as follows: + Dell ST2220T Monitors have been purchased. On first install, the + touchscreen worked pretty well. But it started to behave weird after + restarts. The behaviour is as follows: On cold boot touch never works. But once going to Windows 7 and coming back after a warm boot, the touch works perfectly. From now, it works until there are no cold boots. Once cold boot happens into Ubuntu, touch stops working. This behaviour has been consistent. I tried to put usbhid.quirks with <vendorid> : <productid>: 0x40 as mentioned here http://ubuntuforums.org/showthread.php?p=10287057#post10287057 but it did not work. - I am using Ubuntu Natty + This is on Ubuntu Natty. + + A patch from Red Hat bugzilla: + https://bugzilla.redhat.com/show_bug.cgi?id=703118 seems to help the + issue significantly, but, a few touch features (such as "click") seem to + still need some work. The patch doesn't seem to be upstream yet in the + mainline kernel. + + + + SRU Request: + + Impact: + + Customer currently has 150 of these monitors with plans to expand to 1,500 next year and 10,000 in the year after that. Getting these devices to + work with ubuntu will help out a lot with cost reduction for the customer. + + Patch: + + See bugzilla reference above. + + Steps to reproduce: + + 1) Install 11.04 (In this case the system was dual-booted with Windows 7) + 2) Without the patch, the touchscreen only seems to work if the machine is warm-rebooted from Windows. The touch features don't work at all if the system is cold-booted into Ubuntu. + 3) With the patch, the touchscreen appears to work with cold boots and warm reboots, but, 'click' features on the touchscreen still need to be applied. + + TEST CASE: + + Apply the patch to the kernel, then test the touchscreen after warm + reboots and cold boots to ensure that the touchscreen is fully + functional. Customer has agreed to assist with testing, etc. + + Regression Potential: + + Unknown at this time. Patch appears to be pretty trivial and isolated + so regression potential seems to be pretty low. ** Patch added: "DellST2220T.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/791833/+attachment/2207732/+files/DellST2220T.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791833 Title: Dell ST2220T Monitor responds to touch only on warm boot from windows To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/791833/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
