Public bug reported: [Impact] After system sleep, Goodix touchpad doesn't work anymore.
[Fix] Add a delay after issuing SET_POWER_ON command. [Test] With the patch applied, Goodix touchpad still works after system sleep. [Regression Potential] The original delay between SET_POWER_ON and RESET was increaed to 60ms, so the the driver becomes much more forgiving on power management. Hence I am not seeing any major potential regression risk here. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: High Status: New ** Affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: Won't Fix ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: Won't Fix ** Affects: linux-oem-5.6 (Ubuntu Focal) Importance: High Status: New ** Tags: oem-priority originate-from-1890099 somerville ** Also affects: linux-oem (Ubuntu) Importance: Undecided Status: New ** No longer affects: linux-oem (Ubuntu) ** Also affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Focal) Status: New => Won't Fix ** Changed in: linux-oem-5.6 (Ubuntu) Status: New => Won't Fix ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Changed in: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided => High ** Tags added: oem-priority originate-from-1890099 somerville -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891998 Title: Fix non-working Goodix touchpad after system sleep To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1891998/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
