Thanks Kai. Unfortunately it's still not ok. Interestingly now there is no flickering per-se. What I see is display corruption and flickering when refresh occurs - for example by moving the mouse or typing something.
Is there anything else I can try at this point? Or any further information I can provide? pmatos@cartwheel:~$ dmesg [ 0.000000] Linux version 5.1.0-994-generic (kernel@gloin) (gcc version 8.3.0 (Ubuntu 8.3.0-6ubuntu1)) #201904222200 SMP Tue Apr 23 02:04:43 UTC 2019 [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-5.1.0-994-generic root=UUID=252898e9-6e96-4705-a709-2db930b7c4c7 ro quiet splash i915.fastboot=1 i915.enable_rc6=0 vt.handoff=1 [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] AMD AuthenticAMD [ 0.000000] Hygon HygonGenuine [ 0.000000] Centaur CentaurHauls [ 0.000000] x86/fpu: Supporting XSAVE feature 0x001: 'x87 floating point registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x002: 'SSE registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x004: 'AVX registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x008: 'MPX bounds registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x010: 'MPX CSR' [ 0.000000] x86/fpu: xstate_offset[2]: 576, xstate_sizes[2]: 256 [ 0.000000] x86/fpu: xstate_offset[3]: 832, xstate_sizes[3]: 64 [ 0.000000] x86/fpu: xstate_offset[4]: 896, xstate_sizes[4]: 64 [ 0.000000] x86/fpu: Enabled xstate features 0x1f, context size is 960 bytes, using 'compacted' format. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826125 Title: Dell XPS 13 9380 flickering (Intel Kaby Lake) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1826125/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
