kblinhi folks10:11
kblinI'm currently playing with the 20.04 nightly on an HP Elitebook x360 with an Intel UHD 620 card, and I'm seeing some really bad screen tearing, especially when scrolling10:12
kblinI don't have that issue in a Debian 10 live image, but that in turn doesn't like the WiFi10:12
kblinlooking at the output from "inxi -G", it seems like on the Debian live image, I'm using the modesetting driver for X11, and on focal I'm using the i915 driver10:14
tomreynkblin: have you consdiered 19.10 (20.04 is in development still)10:14
kblinI have the same issue in 19.10, and tried 20.04 because some forum posts suggested that the problem might have been fixed on a more recent kernel10:15
tomreynyou'll be using i915 on both10:15
kblinfunnily enough, I can actually make the problem appear on a Debian 10 install if I switch to a 5.x series kernel :)10:15
kblinin any case I'm not ready to use this machine for production anyway, so I figured that any fix I found would also be applicable to 19.1010:16
tomreynthis was discussed on #ubuntu yesterday - could be related, but a workaround is in anything but focal: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/184558410:16
ubottuLaunchpad bug 1845584 in linux (Ubuntu Focal) "intel-lpss driver conflicts with write-combining MTRR region" [Undecided,In progress]10:16
tomreyni'm not sure this is the problem you're seeing, it *could* be10:17
kblinthat looks like a "fails to boot" issue, my system is booting just fine10:18
kblinI'm not seeing the issue if I use the live system in "safe graphics" mode10:18
tomreyngood point, yes.10:18
kblinso to me this really sounds like an X issue more than a kernel thing10:19
tomreynis anything logged?10:19
kblinI've tried uninstalling the xserver-xorg-video-intel package, but somehow I'm still on the i915 driver10:19
tomreynxserver-xorg-video-intel is the 2d graphics driver for Xorg, you need it. i915 is the linux kernel driver for supporting intel graphics in the first place, you need it10:20
kblinwhere's the X log file these days? shouldn't it be in /var/log somewhere?10:21
tomreynactually seems like i'm misinformed, sorry. you don't need xserver-xorg-video-intel10:21
kblinI mainly uninstalled that because the package description said "you don't need this on hardware from 2017 and newer"10:22
kblinI'm mainly noticing how clueless I've gotten on X11 configuration, because all my stuff has just been working fine for so many years :)10:23
tomreynX logs to syslog / the systemd journal, it may addiitonally log to either ~/.local/share/xorg/ or /var/log/Xorg/10:23
tomreynif you use    lspci -k | grep -A3 VGA    you'll notice the hardware itself is actually driven by i91510:24
tomreynso this you won't be able to replace10:25
kblinyeah, both the kernel line and the X line claim i91510:25
tomreynyour only option there is to fiddle with kernel parameters or to try different kernel versions10:25
kblinI mainly want to try getting xorg to use the modesetting driver10:26
tomreynif you'd like to post your system journal for the current boot i can take a look to see if i spot anything unusual.10:26
tomreynjournalctl -b | nc termbin.com 9999 10:27
tomreynX should be using modesetting on i915 by default for a good while already10:27
tomreyndefinitely with anything including and past ubuntu 18.04, more likely since 14.04 or 16.0410:28
tomreynactually earlier, intel was amongst the first to do it10:28
kblinso what's the "safe graphics" mode for the live image doing, because as I mentioned that works just fine10:29
tomreynit disables kernel mode setting10:29
tomreynyou can always press 'e' at the grub menu to inspect the "linux" line and which parameters are passed to it10:30
tomreynthe "safe graphics" boot option adds the "nomodeset" kernel parameter (on top of the other parameters also used by the default grub menu option)10:32
kblinI'll give that a try, for giggles10:36
kblinalso because the screen refresh issue makes any terminal use super annoying :/10:36
kblinok, the "nomodeset" kernel option "fixes" it, but of course at the cost of not having a proper graphics driver10:44
kblinfunny, now I've set a custom config to try the uxa renderer for the intel driver, and X11 seems to have decided to use the fbdev driver instead11:07
kblinbut it looks like the uxa renderer is enabled and fixes the issues I'm seeing11:11
tomreynthere's the TearFree option to X(org), but i think such issues usually point to the graphics drrievr rather11:26
tomreyn*driver11:26
tomreynbtw. there are several models in this hp elitebook x360 series, with different hardware: https://i.imgur.com/YA4zz5n.png11:32
