Konsole under Jaunty

As noted in several places, some applications feel somewhat sluggish in Ubuntu Jaunty compared with Intrepid if your system has an Intel graphics card.

There isn't a great solution for X in general yet - some options involving X.org tweaks and replacement X packages are discussed here

Applications which render a lot of text seem to be affected quite a bit. For Qt applications there is a simple workaround, in Konsole the workaround makes tab-switching much more snappy. Start Konsole with the raster graphics mode:

konsole -graphicssystem raster

This also works wonders on the Mendeley Desktop research management software which I work on.

Thanks for the hint, Robert :)

It's a shame that Qt4's raster engine is often faster than using X11 directly (rather than side-stepping it) - one of my fondest hopes is that Qt Software will make fredrikh an offer he can't refuse ;)

You know, I have always liked you, until now! I LOVE YOU! I have been batteling with this issue now for weeks, it is much faster all around, thank you, thank you, thank you!

off topic: your software looks great! This is something I have been searching for a long time (everybody thought it was non existent).

So it can extract title, authors, etc.. automatically from a pdf ? Is it possible to incorporate this in strigi as a stream analyzer ?

Awesome! This also makes Kate a lot faster when working with long lines.

I wonder if there is a way to make this the default for certain applications.

I can confirm that adding "-graphicssystem raster" also cures Konsole under the nvidia xorg driver. Thanks for the tip!

I solved the "konsole slowness issue" (Archlinux: I noticed the problem when using yaourt) by limiting the scrollback to 1.000 lines (instead of setting it to "unlimited")

Thank you million times for this advice. I was going crazy about the Konsole slow rendering. I spent like 4 hours playing with it, until I finally read your blog post :-)
