[00:53] <tomf> I installed xubuntu on this old XPS 16 with an ATI Radeon HD 3670 and the fans are running at full speed, despite the temps being normal. Where should I look first to fix this?
[00:57] <well_laid_lawn> tomf:  does it happen with the propriety driver ?
[00:57] <well_laid_lawn> !amd
[00:58] <tomf> I haven't installed that yet. It said it had dependencies -- but then another forum post mentioned that the props weren't supported. I figured I'd ask before moving ahead with that, just in case
[00:59] <tomf> thanks, well_laid_lawn -- I'll give it a swing
[00:59] <well_laid_lawn> luck
[16:26] <xubuntu41w> Hi all, I'm using Xubuntu 18.04 with Staging PPA and currently I cannot login. Some applications crashed, according to /var/crash. Earlier today quite a lot packages were upgraded. Before that login was OK (although I had occasional xfwm or panel crashes, but that didn't impact the functionality). Do you have any idea how I could fix it, or where I
[16:26] <xubuntu41w>  could start troubleshooting?
[16:45] <brainwash> xubuntu41w: check ~/.xsession-errors
[16:46] <brainwash> xubuntu41w: just to clarify: you cannot login or the desktop cannot be loaded?
[16:50] <xubuntu41w> I can login on the tty1 etc. but the desktop is not loaded. ~/.xsession-errors has some warnings and also critical, but those are from my current session (I installed openbox to get an Desktop)
[16:51] <brainwash> ~/.xsession-errors.old for previous session
[16:55] <xubuntu41w> the .crash-files are from xfwm, xfce4-session and Xorg. According to the timestamps Xorg crashed first, then xfwm and xfce4-session later. In .xsession-errors.old ther's some more lines, but I think there also from a later login:
[16:55] <xubuntu41w> (nm-applet:12368): Gtk-WARNING **: 18:02:32.651: Can't set a parent on widget which has a parent(0x7ffcfe6eab50) Warning: The X11 connection broke (error 1).

[16:55] <xubuntu41w> 1 (Resource temporarily unavailable) on X server :0.
[16:56] <xubuntu41w> I could try to login to Xubuntu again and check xsession-errors
[16:56] <xubuntu41w> let me check ...
[17:03] <xubuntu41w> oh yeah, there's a lot: https://pastebin.com/rNSN9TPE
[17:05] <brainwash> ICE I/O Error
[17:08] <xubuntu41w> what about https://bugs.freedesktop.org/show_bug.cgi?id=107117
[17:08] <xubuntu41w> xfwm4: ../src/mesa/drivers/dri/i965/intel_mipmap_tree.c:1285: intel_miptree_match_image: Assertion `image->TexObject->Target == mt->target' failed.
[17:09] <xubuntu41w> today and Mesa upgrade to 18.1 was coming via ubuntu-updates
[17:11] <brainwash> sadly, no clue
[17:12] <brainwash> it does not appear that this prevents xfwm4 from working
[17:12] <brainwash> you could disable the compositor and check again
[17:12] <brainwash> xfconf-query -c xfwm4 -p /general/use_compositing -s false
[17:13] <xubuntu41w> ok. i will try that. what would the ICE I/O error mean?
[17:13] <brainwash> the ICE error could be related to .Xauthority not being owned by your user I think
[17:14] <brainwash> but you are able to login to a different DE/WM
[17:15] <xubuntu41w> (and the mesa-upgrade was from 18.
[17:16] <xubuntu41w> (and the mesa-upgrade was to 19.0.2). yes, I can login to openbox
[17:17] <brainwash> regular update or PPA also?
[17:19] <xubuntu41w> i have some PPAs: Xubuntu Staging, Mongodb and Unifi. But I guess they are unrelated. I will now try disabling the compositor and maybe also using Oibaf-PPA to get another Mesa version
[17:20] <brainwash> downgrading packages should be possible via "sudo apt install <package>=<version_string>"
[17:20] <brainwash> "apt policy <package>" for a list of available versions
[17:20] <xubuntu41w> ah, ok. that's maybe better than upgrading to Oibaf
[17:21] <brainwash> this may be tricky though if a package relies on various dependencies which may need to be downgraded also
[17:22] <brainwash> ppa-purge can uninstall all packages from a PPA
[17:22] <brainwash> and restore the original ones
[17:22] <brainwash> ideally at least :)
[17:24] <xubuntu41w> hmmm, ok. thanks for tips. I will try some things and come back. thanks!
[17:27] <xubuntu41w> great, disabling the compositor worked!
[17:32] <brainwash> so, a problem with mesa most likely
[17:32] <brainwash> compositor tries to use opengl by default
[17:39] <xubuntu41w> would a bug report be useful?
[17:43] <brainwash> xubuntu41w: other than the linked one?
[17:44] <brainwash> (which I did not actually read)
[17:45] <xubuntu41w> the linked one is for Mesa 18.1 and was fixed. Would be interesting if anybody else with Bionic and Xubuntu Staging PPA has the same issue
[18:07] <xubuntu41w> here it is: https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1835622
[18:30] <Heiner1> Hello
[18:31] <Heiner1> Maybe someone may help me
[18:33] <Heiner1> I would like to upgrade xubuntu from 16.04 lts to the newest lts (I guess it's 18.04), therefore I found this description for ubuntu:
[18:33] <Heiner1> https://linuxconfig.org/how-to-upgrade-to-ubuntu-18-04-lts-bionic-beaver
[18:34] <Heiner1> Is it possible to follow the same steps for xubuntu? Or would I have after following these steps an ubuntu-system (and no xubuntu) on my machine?
[18:47] <Heiner1> So could someone help me with that?
[18:49] <brainwash> Heiner1: should work for xubuntu too
[18:49] <brainwash> xubuntu is ubuntu after all
[18:50] <brainwash> xubuntu41w: I suggest that you open a report on the Xfce bug tracker also https://bugzilla.xfce.org/
[18:51] <brainwash> xubuntu41w: that way the xfwm4 dev can look into your issue
[18:51] <xubuntu41w> brainwash: ok, i will do that. thanks for your help!
[18:52] <brainwash> you're welcome
[18:57] <Heiner1> Ah, thank you very much, brainwash. I just wondered, because after putting "sudo do-release-upgrade" to the console, it says it has to download 3.174 MB, 712 new packages are going to be installed. Well I know it depends on what is installed on my system right now (which seems to me not soo much more than the standard XUbuntu-Version), but it seemed to me quit a lot. Well, but if I will have xubuntu after all on my system I will tr
[18:59] <brainwash> >712 new packages
[18:59] <brainwash> quite a big number
[19:23] <Heiner1> Ok, thank you, bye!
[23:02] <tomf> when running sensors, if the machine pauses for a second, is that related to a bios issue?
[23:07] <tomreyn> tomf: the "sensors" CLI from lm-sensors? anything in dmesg when you do?
[23:11] <tomf> CLI
[23:12] <tomf> one sec. checking dmesg
[23:13] <tomf> nothing new in dmesg
[23:16] <tomreyn> tomf: then ... it might be a hardware or firmware or driver issue, or nothing at all. ;)
[23:17] <tomreyn> if you have (other?) reasons to assume your hardware or firmware is affected by anything impacting its stability, you could run benchmarks to rule that out (or proove it).
[23:18] <tomf> for the sake of sanity, let's just assume the latter. I'm not sure which temps the fans are supposed to come on at, but I'm running around 52C on the high end, 43C on the low end, but the fans are constantly running around 2800RPM
[23:18] <tomreyn> you could run a memory test (the current free but not open source variant from https://www.memtest86.com/ )
[23:19] <tomreyn> i'd also suggest you review the system log, espoecially the boot.
[23:19] <tomreyn> + check for ifrmware updates
[23:21] <tomf> ok cool. I'll dig in. This is my old laptop from about ten years ago. Pretty much everything worked perfectly out of the box
[23:21] <tomf> I even have my magic trackpad 2 working like a dream
[23:27] <tomf> thanks tomreyn!
[23:29] <tomreyn> tomf: good luck, don't despair.
[23:30] <tomreyn> if it's the only issue, it's probably not worth it. on the other side, if you have spare time, it's well worth getting a better understanding of this (if it's new to you).
[23:32] <tomreyn> journalctl -b   gets you the logs on currently supported xubuntu releases.
