[10:11] <kblin> hi folks
[10:12] <kblin> I'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 scrolling
[10:12] <kblin> I don't have that issue in a Debian 10 live image, but that in turn doesn't like the WiFi
[10:14] <kblin> looking 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 driver
[10:14] <tomreyn> kblin: have you consdiered 19.10 (20.04 is in development still)
[10:15] <kblin> I 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 kernel
[10:15] <tomreyn> you'll be using i915 on both
[10:15] <kblin> funnily enough, I can actually make the problem appear on a Debian 10 install if I switch to a 5.x series kernel :)
[10:16] <kblin> in 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 19.10
[10:16] <tomreyn> this was discussed on #ubuntu yesterday - could be related, but a workaround is in anything but focal: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845584
[10:17] <tomreyn> i'm not sure this is the problem you're seeing, it *could* be
[10:18] <kblin> that looks like a "fails to boot" issue, my system is booting just fine
[10:18] <kblin> I'm not seeing the issue if I use the live system in "safe graphics" mode
[10:18] <tomreyn> good point, yes.
[10:19] <kblin> so to me this really sounds like an X issue more than a kernel thing
[10:19] <tomreyn> is anything logged?
[10:19] <kblin> I've tried uninstalling the xserver-xorg-video-intel package, but somehow I'm still on the i915 driver
[10:20] <tomreyn> xserver-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 it
[10:21] <kblin> where's the X log file these days? shouldn't it be in /var/log somewhere?
[10:21] <tomreyn> actually seems like i'm misinformed, sorry. you don't need xserver-xorg-video-intel
[10:22] <kblin> I mainly uninstalled that because the package description said "you don't need this on hardware from 2017 and newer"
[10:23] <kblin> I'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] <tomreyn> X logs to syslog / the systemd journal, it may addiitonally log to either ~/.local/share/xorg/ or /var/log/Xorg/
[10:24] <tomreyn> if you use    lspci -k | grep -A3 VGA    you'll notice the hardware itself is actually driven by i915
[10:25] <tomreyn> so this you won't be able to replace
[10:25] <kblin> yeah, both the kernel line and the X line claim i915
[10:25] <tomreyn> your only option there is to fiddle with kernel parameters or to try different kernel versions
[10:26] <kblin> I mainly want to try getting xorg to use the modesetting driver
[10:26] <tomreyn> if you'd like to post your system journal for the current boot i can take a look to see if i spot anything unusual.
[10:27] <tomreyn> journalctl -b | nc termbin.com 9999 
[10:27] <tomreyn> X should be using modesetting on i915 by default for a good while already
[10:28] <tomreyn> definitely with anything including and past ubuntu 18.04, more likely since 14.04 or 16.04
[10:28] <tomreyn> actually earlier, intel was amongst the first to do it
[10:29] <kblin> so what's the "safe graphics" mode for the live image doing, because as I mentioned that works just fine
[10:29] <tomreyn> it disables kernel mode setting
[10:30] <tomreyn> you can always press 'e' at the grub menu to inspect the "linux" line and which parameters are passed to it
[10:32] <tomreyn> the "safe graphics" boot option adds the "nomodeset" kernel parameter (on top of the other parameters also used by the default grub menu option)
[10:36] <kblin> I'll give that a try, for giggles
[10:36] <kblin> also because the screen refresh issue makes any terminal use super annoying :/
[10:44] <kblin> ok, the "nomodeset" kernel option "fixes" it, but of course at the cost of not having a proper graphics driver
[11:07] <kblin> funny, 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 instead
[11:11] <kblin> but it looks like the uxa renderer is enabled and fixes the issues I'm seeing
[11:26] <tomreyn> there's the TearFree option to X(org), but i think such issues usually point to the graphics drrievr rather
[11:26] <tomreyn> *driver
[11:32] <tomreyn> btw. there are several models in this hp elitebook x360 series, with different hardware: https://i.imgur.com/YA4zz5n.png
