[00:00] <ev-nar> When rebooting after install from startup disk, I was told the system couldn't boot, and I had to re-insert the startup disk, after which I got to MOK manager
[00:00] <ev-nar> help?
[00:00] <ev-nar> Which key do I select?
[00:20] <netnomad> Hi.  I'm running 20.04.  When my kernal upgraded to 5.8 my network card (realtek) disappeared.  I've been updating regularly and "going back" to 5.8 a few times a week to see if the problem fixes itself, but it doesn't.  Any suggestions.
[00:20]  * netnomad makes offerings of craft beer to the Linux deities.
[00:21] <netnomad> When I boot in 5.8 it says the network card is "unclaimed" when I run that command that lists the network interfaces whose name escapes me at the moment.
[00:22] <netnomad> kernal 5.4 appears to be comparatively fine.
[00:24] <netnomad> The network card identifies as Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 if that is helpful in any way.
[00:34] <genii> I think it is the 84xx which are possibly problemmatic
[00:49] <netnomad> I guess I'm SOL.
[02:50] <indyZ> So, I've been having this problem with Xubuntu where, when I close my laptop to suspend, when it comes back my mouse/keyboard doesn't work.
[02:50] <indyZ> Just figured something out: If I type in my password, as if I'm at a lock screen, and hit enter, my mouse and keyboard work again.
[02:51] <indyZ> so it seems that I am at the lock screen when opening the laptop, even though I see my desktop instead.
[08:52] <anotheryou> Hi. I got some misbehaving apps that hog CPU. Can I somehow lower the nice value of whatever does mouse keyboard and terminal? I can't even rescue myself to htop.
[08:52] <anotheryou> is that a reasonable approach after all :)
[08:52] <anotheryou> ?
[08:53] <anotheryou> and vice versa, should and can I make the misbehavers be more nice by default?
[12:06] <David-A> anotheryou: do you know what program is misbehaving / using cpu?
[12:12] <fernando-basso> apt dist-upgrade stuck at pepperflashplugin-nonfree. Is this any known issue?

[12:19] <xu-help87w> I am looking for the location for lightdm.conf in 20.04 but can't find it. Any clues?
[12:21] <diogenes_> xu-help87w, /usr/share/lightdm/lightdm.conf.d/
[12:21] <diogenes_> it's all snippets.
[12:23] <xu-help87w> Thanks.
[12:24] <diogenes_> np
[12:26] <xu-help87w> Well, I need to custom set the resolution of the login screen (HiDPI display) so I thought I set 'display-setup-script' to a script I wrote - into which snippet do I put it?
[12:31] <diogenes_> xu-help87w, you can write your own, something like: 40-resolution.conf
[12:31] <diogenes_> [Seat:*]
[12:31] <diogenes_> greeter-setup-script=yourscript
[12:34] <fernando-basso> brainwash: Thanks.
[12:51] <xu-help87w> Works. Thank you!
[12:52] <diogenes_> you're welcome.
[14:19] <anotheryou> David-A: mostly the proprietary crap: MS teams, spotify, telegram, sometimes signal
[14:20] <anotheryou> I'm wondering why the basic OS (mouse, keyboard, window manager, maybe terminal) does not take priority over them.
[14:22] <David-A> anotheryou: if you allow me to guess. 2 answers.
[14:24] <anotheryou> sure :). Thanks for helping.
[14:24] <David-A> anotheryou: if you have programs that do productive work, like a server or something, then you may not want the gui to block the services just because you start a heavy gui program or move around or resizing windows. what kind of programs to have priority may differ for different users.
[14:25] <anotheryou> I see. Makes sense indeed.
[14:26] <David-A> anotheryou: if you give the terminal and the shell higher prio, then a "while true; do :; done" or a typing error in a terminal may block the system.
[14:27] <anotheryou> I just want it above other programs I launched
[14:28] <David-A> anotheryou: but it you have apps that missbehaves, maybe lowering their prio may help you.
[14:29] <anotheryou> David-A: exactly. I was looking at nice, renice and maybe even "automatic nice deamon (and)". But they all are complicated to configure and I wondered if I'm even on the right track :)
[14:30] <David-A> anotheryou: have you concluded that it is cpu load that is the problem and not virtual memory thrashing or something else?
[14:32] <anotheryou> David-A: yes
[14:32] <anotheryou> David-A: but haven't excluded that first memory runs full and than it's cpu or something
[14:37] <David-A> anotheryou: i sometimes have trouble when i have houndreds of tabs in firefox, that virtual memory becomes full, and mouse and terminal interaction becomes painfully slow. can take 1/2 hour to change focus from the browser to a terminal.
[14:37] <anotheryou> David-A: Something like that, exactly. would want to avoid that
[14:40] <David-A> anotheryou: theoretically, there are ways to limit the amout of virt mem a program may use
[14:45] <David-A> anotheryou: if i recall correctly, the bash command "ulimit" helped when firefox was a 1 process program, but it doesnt limit it now when it has multiple processes. i don't know what command you'll need
[14:52] <anotheryou> I might try "and" just not sure how I refer to my programs correctly. In htop I see some path with "snap"
[14:52] <anotheryou> and than launching stuff as root on startup... it's all a bunch of config work I'm a bit hesitant to dive in to
