Try with:

Code: Select all

sudo apt-get install xorg libgl1-mesa-glx libgl1-mesa-dri mesa-utils

then check with glxgears if it actually draws something.

Optional:

Code: Select all

sudo nano /etc/inittab

in the lines around 54-60 something, so quite at the bottom, you can either remove or change the 8th tty that run's a screensaver (tty-clock) to look like:

Code: Select all

6:23:respawn:/sbin/getty 38400 tty5
#8:2345:respawn:/sbin/getty 38400 tty8

(with or without comment, as you wish)

[rhowaldt]

sorry Jules, the apt-get thing didn't do any good. i now notice Xorg sometimes even taking up 52% :/ - glxgears gives me pretty gears, but chromium is visually borked. i remember seeing something like that before, when experimenting with graphics drivers through smxi. my laptop has a Radeon Mobility HD2400 and that doesn't seem to be supported by much good shit. i have no idea what else this issue could be but a video driver thing...

[rhowaldt]

could the cpu use have anything to do with the fact that my laptop needs a fan cleaning? it is supernoisy and perhaps that makes stuff run less well? is this possible? i have never had to deal with this before, this is the first laptop i have that i've been using for this long. but one of the biggest reasons i want the cpu thing fixed is simply because my laptop is noisy as fuck and it is no longer a joy using it when inside X (which is why i've been looking into framebuffer stuff).

[machinebacon]

^ Could be, yes. Would be interesting to install lm-sensors and check the CPU temp. ("sensors") - to see if the CPU is actually hot or just the fan not under control. If latter, maybe try to get a fan control (for example, if it's a Dell, 'i8kutils', for IBMs it's 'thinkfan').
I'd recommend, for the quick, to go back to an older kernel (check antix around the 3.14 mark maybe), we have experienced much much higher CPU usage with newer kernels. You could also use cpufreqd and cpufreq-utils with powersave governor to make the laptop chill down a bit.

[rhowaldt]

Jules, thanks for the answer. i just did all that except for the fan - it's a Packard Bell, which is Acer it seems. haven't yet been able to make fancontrol work.
and did cpufreq-set -g powersave as you said.
so far it doesnt seem to make a difference.

i still have the fucked up graphics everywhere, most noticeably in Chromium. i'm not sure how to revert to what i had (where the graphics were good) after your earlier suggestion. still have to look into the 3.14 antix kernel, using 3.17 liquorix now.
any help much appreciated :)

[rust collector]

Here are links to the 3.14.0 antix 486 kernel, and headers, if you want to try that.
(Just sudo dpkg -i them, after downloading, then update-grub)

A bar and/or a panel using up 14% of CPU seem to be quite high IMO. For kicks, can you run this setup without panel/bar/loops, just to see if it makes a difference. Also, as for running the chrome-ish browser, can you run it like this from a terminal and check if the CPU usage stays lower:

Code: Select all

chromium --disable-gpu

kilall -SIGUSR1 lemonbar reduces Xorg CPU again, and restarting the panel with "herbstclient reload" boosts it back to 40%. wtf. why didn't it do that before the reboot?

i think we found the culprit, then? seems i need to reprogram my damn panel again :|

^ Hmm, maybe Drew knows something, He has used Herbstluftwm for quite some time I think ( or at least tinkered a bit with it).

[dkeg]

I don't think I have much to add here. One thing I can say is these system info bars can create a lot of extra strain on the system/cpu. With my bar now it is not bad, I use sleep .5, and that is a good balance of 'immediate' and happy system. If I get rid of that, and my calls are constant, cpu tells me. It's just too much. I also find it takes some time for the fans to calm down.

Take a session with no bar. See how that is. Use my popup rendition to you can have stats on call, or use osd_cat which I think you already have.

You can also just for kicks take someone else's bar script; you can have mine if you want, I'll need to post it though as its different than the popup rendition I posted in the bar thread.

So no bar is your baseline, someone else's bar is the control; you bar is the raw experiment.

Having fun yet!

rho, you can remove the 'libgl1-mesa-dri' again, I don't include it on purpose :) If doing so, drop 'mesa-utils', too -- because glxgears won't work anyway :)

Time for Openbox again :D

@Drew: indeed - found that my old panel.sh, which uses dzen, works great now and with less cpu, while doing everything i want except for using the siji icons. instead, i can use xmb icons directly, so it isn't that big a deal. will continue experimenting :)

@Jules: thanks, will have a try and report back!

[rhowaldt]

thanks again Jules, that fixed the GUI glitches! all back to normal now :) marking it SOLVED.

one more question: when removing libgl1-mesa-dri it also removed xorg. i stopped the process halfway through Ctrl+C (probably shouldnt have done that...). all seems fine except i have to start my wifi manually each time with "ifup wlan0" - ceni doesn't see my wlan0 anymore for some reason (or my eth0 for that matter). tried reinstalling mesa-dri and xorg, then remove the mesa-dri again, but it keeps asking to remove xorg with it. what would the best course of action be in this case?

[dkeg]

for bringing up wireless. YOu can add

Code: Select all

sudo ifup wlan0

to

Code: Select all

/etc/rc.local

before the exit 0

IIRC, xorg is not needed?? Do IARC that some of the base installs do not even come with xorg installed?

Oh, and you could probably let xorg uninstall, then reinstall xorg.

[machinebacon]

^ strange, I don't have xorg installed, so I cannot really pin it down for you...

And xorg has nothing to do with network connectivity, it's just a kind of metapackage that pulls in a few things (check 'depends xorg'), so removing xorg alone should already purge libgl1-mesa-dri. Try doing this, then shutdown the computer, then start it again cold, set up ceni once, then reboot. I can only imagine that a previous shutdown or reboot was stuck somewhere.

You can, if nothing else works, add

ifup wlan0

or whatever command you need in /etc/rc.local before the "exit 0". Hacky, but ... just trying to find a fix for now :)

Edit: what drew said :)

Edit 2: drew, xorg (as metapackage) is not xserver-xorg :) if somebody doesn't want Mesa, he or she can pick that one.

thanks for the info guys. i've removed libgl1-mesa-dri and xorg and rebooted, and all looks good now.

only thing is the wifi. when using ceni it reports "no values" under "Hardware interfaces" - does give wlan0 under logical interfaces, but i have no idea why this changed. will check it out further and do the hack in the rc file otherwise because fuck it.

^ Maybe it is this:

https://bugs.debian.org/cgi-bin/bugrepo ... bug=787263

Ceni could be affected.
A patch is on its way if you use the newest systemd.
Maybe I am just shooting into the dark.
