konsole running very slow [solved - workaround]

donmartio · Apprentice Joined: 11 Dec 2004 Posts: 261

Next round...

I build a little ebuild of xorg-server with the special config param --disable-builtin-fonts (somebody mentioned it in a debian forum somewhere).
But nothing changed.
I also tried the xorg radeon driver but with this one i obviously can't use my two tft without jumping through some more hoops.
I can't downgrade to the old xorg server.
Is there anybody out there with some special trick?

Any help appreciated.

Greetings DonMartio

Ho, thanks for the reply. I tried with compiz enabled with no better results. Maybe i am doing somthing wrong with it.
Do you have aiglx enabled or any other special xorg.conf things?

Many thanks and Greetings

Well, thanks anyway.
I tried to compile with freetype enabled (fishing in the dark) but except from some weird console problems this does nothing.
It seems i have to dig a little bit further.

Ok, i'm out of options now. At home with my nvidia card... no problem.
But here at work with an ati card it's so slow that i sometimes think i'm working on a HP-UX terminal
in the middle 90ies.
I tried some compile options now buy fiddeling around with a copy of the xorg-server ebuild. But i think it must be something with xorg-server-1.5.3 and the ati-drivers together. At home i run xorg-server now since... i don't know when... and everything is smooth.
And at home i have an 5 years old amd64 pocketcalculator.

There must be anything i can do? I have a lot work to do on the console.

So if anybody with an ati card has a smooth running system with xorg-server-1.5.3 please tell me why.

Many Greetings

So just for the records... i tried kde4.2.1 now and besides some trouble getting it to work everything is quite smooth now.

So it seems it's not xorg-server alone causing all the slowness.

I don't have an explanation for this but as long as it works i don't mind.

Hi all,

I am having the same problem: KDE's konsole scrolls slow and uses 100% CPU doing so for long texts.

I have an nVidia GeForce 8600 GT, and the problem appears with both nv and nvidia (from x11-drivers/nvidia-drivers) drivers, so the problem is not necessarily tied to ATI. As far as i can tell, the problem began when i restarted X after the recent upgrade to 1.5.3-r5 from 1.3.0.0-r6. My x11-drivers/nvidia-drivers version is 180.29, and i am not using compiz. Forcing the DPI to 96, as someone suggested, did not help.

My kernel is 2.6.27-gentoo-r8 (but i did not have the problem with 2.6.25, so it's not a problem with kernels past 2.6.22, as someone suggested).

Two interesting things:

1. The problem disappears when i select certain fonts (from konsole's Settings -> Font -> Select). For example, "Fixed [misc]", as someone else suggested, goes fast. Not sure whether the slow fonts are all TrueType, as someone suggested (how can i tell?)

2. The problem also disappears when i disable anti-aliasing (from the Control Center's Fonts dialog). But this looks ugly, so i hope it's just a temporary workaround.

I am not prepared to install KDE 4 at this point. So i would really appreciate it if someone in the know could help solve this serious issue for us who use konsole a lot. I see there is already a bug opened for this issue:

https://bugs.gentoo.org/show_bug.cgi?id=265137

Thanks!

After some time using xorg-server 1.5.3 I also have noticed increasing slowdowns in konsole even under compiz.

I've been using yakuake, which is a Quake-style console that embeds konsole as a kpart inside it, this past week. I have not noticed any slowdowns. It's sort of nice too; took me a day to get used to the "F12" show/hide functionality, but I like how quickly I can get it out of my way and back again.

Anybody out there using yakuake?

Hi,

I got the same problem and I am using either the intel driver, either the mesa one.
I did not try yet to change the fonts, but you can be sure it is not only linked to nvidia or ati.
As soon as I have some time to try, I will test your different advices (change fonts, ...)

FWIW, my Konsole is slow again. Possibly even slower than before.

When the CPU is under load, it can take maybe 1.5 to 2.0 seconds to refresh a maximized Konsole, top to bottom. I don't understand what's going on.

Ah, I think I have the same problem: https://forums.gentoo.org/viewtopic-t-762164-highlight-slow+fonts.html

It is really annoying. Makes me deeply regret the last round of emerges I made.

It used to be so fast... too bad I don't know how to "checkpoint" the version numbers of all my packages, I would downgrade to what I had before to make this fast again.

I have solved the slow font problem for me. When I upgraded xorg, I regenerated xorg.conf, but it had no acceleration enabled. It was all gone from xorg.conf. See https://forums.gentoo.org/viewtopic-t-762164.html

Strangely enough, without the acceleration, enemy-territory FPS improved a bit on some of the maps that were unplayable due to low FPS. I have not tried ET with the EXA acceleration yet.

Hope this works for you.

Nope EXA didn't help me. EXA is default for the intel driver anyway.

I just upgraded to stable kde 3.10 and this issue is solved.
(quite impressive to see konsole going at lightspeed when you were used to see it struggle with output)

That doesn't seem to help 100%. I think Konsole speed [for us with the problem] is dependent on the current CPU load and RAM usage.
