Hi all,
I was listening in on the last irc meeting and caught an aftermeeting
mentioning about bad Qt4 performance. I offered an article and a possible
workaround I found recently, in case people are not aware of it, and was
asked to bring it to attention to other developers also, so here goes:
I'm suffering bad graphical performance in Qt4 and PyQt4 applications and
searched for solutions. I found a post on nokia.com [1] that mentions a
command line switch that might help.
In short: adding "-graphicssystem raster" to my Qt4 applications' command line
improved performance drastically for me. There's also a method to set it
programmatically, and an environment variable [2].

Thanks and much regards,

Hello
In order to help improve TDE, I want to tell my experiences with TDE starting
from a clean install of Debian Squeeze minimal (within X) from the viewpoint
of a Spanish desktop user. The problems, pitfalls or things I've found are
improving (I report all as bugs in the bug tracker to be systematic):
1. Trinity Webpage could be translated into several languages without much problem,
I think there are collaborators with enough time and desire to make it viable.
A call to collaborators through the mailing list to create working groups could
be. I offer to help as Spanish-spoken.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1220
2. Debian installation intructions improvements:
* Refers to "sudo", but Debian as a "su" distro by default, like most distros.
If you're a newbie and follow to the letter the instructions, the lines with
"sudo" not work
* Lack reference to the translation packages, example "For Spanish translate,
apt-get install kde-trinity-i18n-es"
* For laptops, kpowersave-trinity is essential, it shoul be indicate in the
intructions as "if you have a laptop..." or similar.
* A graphical network manager as network-manager-kde-trinity is very util, it
shoul be indicate in the intructions as "if you want to have a graphical network
manager and you are not using a other as wicd, you..." or similar. May notice
about network-manager versions incompatible with network-manager-kde-trinity.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1221
3. Applications of interest:
* Kmix should be in the System Tray.
I don't report, I think is reported in
http://bugs.trinitydesktop.org/show_bug.cgi?id=503
* IMHO k3b-trinity and kima-trinity should be in the default TDE installation,
are useful for the general public.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1222
4. Kpersonalizer:
* Keramic theme is broken, not see the title bar of the windows or close/maximize
/minimize buttons.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1223
* Kpersonalizer is partially in English despite having chosen Spanish. I can
help with it.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1225
* Keyboard in English despite having chosen Spanish in Kpersonalizer. I have
to do KControl > Keyboard Layout > Enable keyboard layout & Show indicator for
single layout.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1224
5. Parts of the system are in English, lack of a complete Spanish translations.
For example, "Hibernate computer" and "Suspend computer" in the "End session"
window.
I can help with it.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1225
6. KDM problems:
* KDM don't draw well the background, artifacts can be seen. I think I solved
it with KControl > System admin > Login manager > Apparance > Compositor: Trinity
compositor. If choosing Trinity Compositor solve the problem, the package
should be reconfigured to do it by default.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1226
* "Finish actual session" in "End session" window dialog don't work, just a
black screen appears instead of KDM. Doing Ctrl-Alt-F1 & Ctrl-Alt-F6, the KDM
window is visible very briefly. I read something similar, related with graphic
card (this is a Nvidia, and use the nouveau driver), I don't know. Related:
In Exe GNU/Linux, a Debian live CD distro with TDE as desktop environment:
* In a live session, if you choose "Change session" in the TDE exit dialog,
you find a KDM login window answer you about user name and password - could be
auto-restart
the TDE desktop
* In a HD-installation session, the KDM login window option "Reboot" don't work,
the system stays in terminal login (you can insert your user name and password,
and the
system remains in terminal modex", you can use "startx" :P )
http://bugs.trinitydesktop.org/show_bug.cgi?id=1227
Possible related with
http://bugs.trinitydesktop.org/show_bug.cgi?id=59
and
http://bugs.trinitydesktop.org/show_bug.cgi?id=419
7. Sudo problems: In a recent mail ( "Clean TDE of Kubuntu references",
http://trinity-devel.pearsoncomputing.net/?0::9879 ) I did a review of the
problems derivated of the Ubuntu reminiscences dragged by TDE project, as
sudo-dependence of TDE nonexistent in the KDE 3.5 original. A set of new
sudo-related bugs:
* Konsole as SuperUser: T > System > SuperUser > Konsole: a Konsole window
appears ask for "[sudo] password for [user]" - it is a Debian (no-sudo) system,
therefore neither user password (user is not in /etc/sudoers) neither root
password (demand sudo) work. Konqueror as root in the "T > System > SuperUser"
dialog works well.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1228
* In T > System, other applications as KPackage open, but for a action ask for
"SUDO password", and again neither user password neither root password work.
But KUser in T > System work well with root password.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1229
* I installed Synaptic. But Synaptic in T > System don't work to enter the root
password. Synaptic via "Run command" answer "KDEInit could not launch
'su-to-root': could not find 'su-to-root' executable". However, "kdesu synaptic"
works well.
http://bugs.trinitydesktop.org/show_bug.cgi?id=1230
8. I suggest the following changes in file associations (in Konqueror:
Preferences > Configure Konqueror)
* Kwrite instead of Kate for plain-text files - I think Kwrite is simpler
* Iceweasel instead of Konqueror for HTML files
http://bugs.trinitydesktop.org/show_bug.cgi?id=1231
Thanks!
All,
I recently pushed a new (alpha quality) backend for the media:/ kioslave
which uses udev/pmount and therefore does not rely on HAL. I encourage
developers here to try it out!
Please report failures to this list, not to the bugtracker, as it has not
been tested much beyond mounting simple flash drives. Encryption support
is buggy, but repairing it is my next task.
Rhis will NOT be made default for R14.0 due to the vast array of hardware
that it still needs to be tested on, but if your distribution no longer
works with HAL it may be better than nothing even in this alpha form.
To enable it, pass the -DWITH_TDEHWLIB="on" option to tdebase CMake.
Enjoy!
Tim
To the local image wizards:
The following files eventually will be renamed to chalk*, but they still need branding work, before or after renaming.
/opt/trinity/share/icons/crystalsvg/128x128/mimetypes/krita_kra.png (Deleting the "K" logo will be sufficient)
/opt/trinity/share/icons/kdeclassic/48x48/apps/krita.png (Change the K to C?)
/opt/trinity/share/icons/kdeclassic/48x48/mimetypes/krita_kra.png (Change the K to C?)
/opt/trinity/share/icons/mono/scalable/apps/krita.svgz (Deleting the "K" logo will be sufficient)
Thanks!

Hey guys,
Thanks to the hard work of our excellent team members 3.5.13 SRU is
almost ready to be released.
Slavek has mentioned a tentative release date of October 1st, which is
a week away.
So we need:
1. A press release ready and have a list of people we want to send it
to. That list has already been compiled. Here is a link to the press
release etherpad. http://trinity.etherpad.trinitydesktop.org/55
2. Sync'd mirrors - Slavek, Tim, is there enough time to do this in 1
week or should we push release back further?
3. Updated website - Tim - what do I need to do to make this happen?
4. Updated wiki - We should make sure we aren't leaving any gaping
holes here on the wiki about 3.5.13 SRU.

What is the proper way to revert my local GIT repo to a specific date (commit)?
I want to modify the sources as they would have looked on a specific day.
I've read to run git reset --hard {HEAD} where {HEAD} is the commit to rest. Does that command truly reset the repo? That is does the command only reset indexes and leave the sources intact or are sources modified to that specific commit and all subsequent pulls are deleted?
I realize that resetting my local repo will mean a bandwidth hit when I restore everything. :)
Darrell
Attention, attention, last call for patches that want to fly with flight
number 3.5.13.1.
I would as soon froze source code for release 3.5.13.1. Please decide if we
should incorporate before freezing any more patches. Definitely will be
integrated patch to sets the version number. Like other candidates I see:
k3b: Update libisofs to read files greater than 2GB
This partially resolves Bug 1111
http://git.trinitydesktop.org/cgit/k3b/commit/?id=8ade4e21303eb4feed76a9d8b…
tdepim: Fix the addquotes/removequots functions
Attachment 826 in bug report 1235
http://bugs.pearsoncomputing.net/show_bug.cgi?id=1235
But, I am not sure if these patches are ready to include for 3.5.13.1.
Your opinion?
Any other patches?
Many thanks,
Slavek

I understand wanting to grab CPU time from the servers to build packages, but the commit patches web page has not been updated in 10 days. We're flying blind.
Can we get the page updated?

Some of you might find this interesting...attached is a screenshot of TDE
running on actual (physical) ARM hardware!
To accomplish this I used Debian Squeeze with TDE running on a Raspberry
Pi over tightvnc. I did need to disable artsd due to some kind of ALSA
bug on this hardware, but this was a minor inconvenience.
Next steps include testing Debian Wheezy and trying to get the built-in
graphics hardware running with Xorg.
Let me know what you think!
Tim
