Freezing in Awesome wm

br flag
The.Wolfgang.Grimmer

I'm always experiencing freezes and slowdown in Awesome WM. You can't even go to the virtual terminal to investigate, so all i have to do is shutdown the laptop by holding the power button. The freezing has been happening more frequent than before.

How do i investigate what causes such problems?

Upon just investigating, i've stumbled upon this file ~/.xsession-errors The contents are posted below. I don't have much know-how to decipher those errors.

You need to use the power button? If SysRq commands don't allow a safe shutdown (closing *fs* to reboot/poweroff etc) then you have kernel issues and it's not related to a WM freeze, but more serious. Is there a reason why you're not safely shutting down & resorting to power button? (*or aren't aware of the SysRq key which allows you to command the linux kernel directly & safely*?) as that's useful detail on system health.

@guiverc i'm pretty new to linux so i have minimal knowledge of some things. Yup, i'm not aware of SysRq, what does it actually do? Is it sort of similar to CTRL+ALT+DELETE in windows?

No very different; REISUB is the most common command; but if you don't remember the commands, grab a phone and search "magic sysrq" and the wikipedia article is usually at or near top (https://en.wikipedia.org/wiki/Magic_SysRq_key) which is as good as any on what command choices you have (ie. saving you from remembering commands like resiub/reisuo etc). It allows you to directly command the linux kernel (would work on a android phones too if you had a real keyboard attached; and not on-screen keyboard that requires GUI to be operating!). You use letters to give commands; the REISUB is 6 cmds

thanks a lot, i will first try to digest everything. It's pretty exciting and daunting to fully use Linux after coming from Windows. :)

also fyi: SysRq is a key on keyboards; however many *modern smaller* keyboards don't have SysRq printed any longer (it was printed in color on the front of the PrintScreen key) and often requires an additional Fn & you to know where the key is positioned (eg. dell 2020 & 2021 models don't have it printed), but if you know where the key is on an older key; you'll find it still works even if printing isn't put on modern keyboards.

yup, so far i've stumbled upon the combination required for Dell machines https://askubuntu.com/a/343750/1389504 and also in this tutorial about SysRq https://www.youtube.com/watch?v=ZiX327d8Ys0

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
