[Ubuntu-x-swat] [Bug 1872192] Re: xserver-xorg-video-intel causes screen flickering in plasma on XPS 15 7590
You are so right, my apologies. This bug report can be discarded. In my efforts to get everything working on a new installation of Kubuntu over the past few days, I unknowingly enabled the Intel driver for XOrg. Unknowingly because: I assumed I was already using it. I put in a config snippet in /etc/X11/xorg.conf.d/20-intel.conf in a (failed) attempt to fix the screen brightness controls. This specifically links the PCI address and the intel drivers. I now removed that file, re-installed xserver-xorg-video-intel package and no flickering. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1872192 Title: xserver-xorg-video-intel causes screen flickering in plasma on XPS 15 7590 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1872192/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1872192] [NEW] xserver-xorg-video-intel causes screen flickering in plasma on XPS 15 7590
Public bug reported: I have been experiencing screen flickering related to the compositor in KDE / Plasma on Ubuntu 19.10 on my Dell XPS 15 7590 laptop. I found the same problem + a solution here: https://www.reddit.com/r/kde/comments/f7itw4/plasma_flickering_neonkubuntu/ It turns out that even though I do have Intel chip (IGP on Core i7-9775H) using the Intel driver i915, the package xserver-xorg-video- intel doesn't seem to be required and does cause screen flickering. Removing this package as suggested on reddit fixes the flickering issue for me and so far I didn't seen any negative side effects - all 3D rendering still works. Either xorg-video-intel package should be solved to not cause flickering (and have effects where it is not needed) or it shouldn't be installed by default. ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1872192 Title: xserver-xorg-video-intel causes screen flickering in plasma on XPS 15 7590 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1872192/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1569383] Re: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode
Just to update: where I said 'turned off by default' I realized I don't actually know what I'm talking about. I never had a Optimus-laptop before, and I never worked with Bumblebee or the like. Therefore I don't know what the state is, and/or how this is supposed to work. Ideally, of course, the nvidia-card would power up and down based on graphic load or application profiles, just like in Windows, but I'm thinking that's not going to happen for a while. With the current situation where you need to switch in between login sessions, at least I'd expect that if I used prime-select or nvidia- settings to switch to IGP, it would actually turn off the nvidia card. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1569383 Title: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1569383/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1569383] Re: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode
You're right, my nvidia card is not turned off. /rpco/acpi/bbswitch listed it as on. Battery usage was better than before, though. Maybe because when not actually using the GPU, it at least scales down to a lower frequency, conserving power (because an additional issue, most likely related to the nvidia drivers, is that the nvidia card always runs at max speed and never turns down. Maybe this is because I'm using a UHD display, not sure. No way to check when running in IGP-mode). Running the command rmmod nvidia_drm nvidia_modeset nvidia_uvm nvidia gives me a notice that nvidia_uvm is not loaded but does unload the other modules. After that I am able to turn off the nvidia card using the command you provided. Battery usage then drops from around 32 Watts to around 19 Watts in idle, so that's a significant improvement. I can't reproduce your crashes when running lshw or lspci, though, they all run fine, even after turning off the nvidia card. Also running something like phoronix-test-suite is fine, the system remains stable. Maybe that's a difference in kernel and/or nvidia driver versions? I've tested using both linux kernel 4.6.0-040600-generic (4.6.0-040600.201605151930) and 4.4.0-23-generic (4.4.0-23.41), using nvidia-364 (364.19-0ubuntu0~gpu16.04.3). Would be very useful / good for battery performance if the nvidia card would be turned off by default. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1569383 Title: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1569383/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1569383] Re: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode
I just installed kernel 4.4.0-23.41 from xenial-proposed and it seems to include whatever alleviated this issue. My laptop isn't crashing anymore. There is the occasional glitch: sometimes when I enter my password at the login screen, the screen will actually not redraw at stay at the login screen while the contents seem to have changed. Moving my mouse cursor actually changes the cursor depending on what should be underneath. Switching to anther VT and back to X.org redraws the screen and fixes it. Also the title bar sometimes gets garbled. Moving or resizing the window fixes that. I did h experience these issues with 4.6 too, by the way. All in all, it's definitely usable this way! -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1569383 Title: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1569383/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1569383] Re: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode
FWIW: today I installed kernel 4.6.0-040600-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/ on my Kubuntu Xenial setup. On this kernel version the nvidia-drivers I was using, nvidia-361, didn't work anymore (it said that kernel 4.6.0 was not supported), so I upgraded to nvidia-464 from https://launchpad.net /~graphics-drivers After this I had one more glitch, that is that even though nouveau is listed in /etc/modprobe.d/nvidia-graphics-drivers.conf as blacklist nouveau blacklist lbm-nouveau it would still be loaded, preventing the nvidia driver from working properly. By adding nouveau.blacklist=1 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub I could prevent it from loading. Using this combination, I now have a fully working optimus setup. I can switch using nvidia-settings between nvidia and intel graphics and both run equally stable. It seems this issue was fixed in kernel 4.6.0 (possibly related to kernel bug https://bugzilla.kernel.org/show_bug.cgi?id=109081). I'm fairly certain that the newer nvidia driver doesn't influence it as even without that, the intel driver would work fine on 4.6.0. I just couldn't switch to the nvidia GPU. Will kernel 4.6.x make it into Xenial at some point? It seems that it's might be required for Skylake laptops to work completely. ** Bug watch added: Linux Kernel Bug Tracker #109081 http://bugzilla.kernel.org/show_bug.cgi?id=109081 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1569383 Title: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1569383/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
