When this happens do you see any relevant messages in dmesg ? In: https://bugzilla.redhat.com/show_bug.cgi?id=1644013 There is a report of the machine sometimes reporting: [ 5.739281] irq 7: nobody cared (try booting with the "irqpoll" option) [ 5.739284] CPU: 5 PID: 0 Comm: swapper/5 Tainted: G C 4.19.2-301.hdg1.fc29.x86_64 #1 [ 5.739285] Hardware name: HP HP ENVY x360 Convertible 15-cp0xxx/8497, BIOS F.21 10/19/2018 [ 5.739285] Call Trace: [ 5.739288] <IRQ> [ 5.739294] dump_stack+0x5c/0x80 [ 5.739297] __report_bad_irq+0x37/0xae [ 5.739298] note_interrupt.cold.9+0xa/0x69 [ 5.739300] handle_irq_event_percpu+0x6a/0x80 [ 5.739301] handle_irq_event+0x27/0x44 [ 5.739302] handle_fasteoi_irq+0x7f/0x120 [ 5.739305] handle_irq+0xbf/0x100 [ 5.739307] do_IRQ+0x49/0xd0 [ 5.739308] common_interrupt+0xf/0xf [ 5.739309] </IRQ> After which the kernel disables IRQ 7 causing the touchscreen to not work again. If you're seeing this too, please open a new bug for the "irq 7: nobody cared" problem. The patch fixing the IRQ not being assigned to the GPIO controller has been merged upstream now, so I'm closing this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752437 Title: [HP ENVY x360 - 15-bq102ng] Touchscreen does not work To manage notifications about this bug go to: https://bugs.launchpad.net/kernel/+bug/1752437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
