I personally wait for the first rc of the .39 kernel in order to test the upgraded nouveau driver. It works surprisingly well with OpenGL ES.

Akonadi problem fixed, I was using qt-debug which hadn't been updated and conflicted with the new mysql. Thanks

I have now Desktop Effects running: After removing every config I found and reboot it worked

Would be fine if next release could include EGL && OGL (maybe compiled with GCC 4.6 )

seems everybody use nvidia.
so I came with an ati report:
default kernel, mesa-git
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV620
OpenGL version string: 2.1 Mesa 7.11-devel
OpenGL shading language version string: 1.20

Effect works quite well, althought need some adjust (openglisunsafe = false).

When will we get our next update? *beg*

Sorry, I've been busy this week. I'll make a new snapshot during next week

Btw, I've tested Gnome3 in work this week and I must say that I'm really really happy that we have something as godamn cool as KDE You remember people crying about lack of usability and stability of KDE4? What a piece of crap it was? Well, I tried Gnome Shell and after like 20 minutes, when I really wanted to start doing some work again I realized that I'll rather revert to Gnome2 . The only thing which is better in Gnome3 then was in KDE4.0 is, that Gnome3 is really very stable. I think it's because they've removed so many features, that there's actually nothing to crash...:)

benneque · 2011-04-01 18:40:54

No problem. Is there somewhere a wiki how to simply generate my own KDE packages? I'd like to use GCC 4.6 with -Ofast and native architecture
You compile with O2 and generic, right? GCC 4.5?

git clone git://gitorious.org/kde-snapshots-repo

Adjust you CXXFLAGS in /etc/makepkg.conf and run create-sources and then build-packages script. But beware that you will probably need to do some hacking in order to successfully compile tha packages. And I admit that the scripts are little messy, since I mostly do "write-only" bashing

GCC 4.6 was pushed to repos just after I compiled the last snapshot, but the next one will be built by GCC 4.6. I'll consider -Ofast, but I really can't build architecture specific packages of course

benneque · 2011-04-01 22:21:53

Yeah, cool!
Up-to-date packages with up-to-date opcode

What were your last C(XX)FLAGS ?

EDIT: Do you know what flags and compiler version the "normal" Arch Package maintainers use?

I use these for x86_64:

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe"
CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe"

For i686 just replace the x86_64. The same flags and settings are used for official packages too.

It's a drawback of binary distributions, that you need to build the code in way which is compatible with as much processor archs and families as possible. On the other hand, it saves lot of time and it's greener I'll take a look on what's new in GCC 4.6 and try to apply as much optimizations as possible without loosing compatibility or performance on other archs.

benneque · 2011-04-02 06:54:21

New in GCC 4.4 (or was it 4.5) was: parallelization-optimization (it's called "Graphite"). Flags are:
-floop-interchange
-floop-strip-mine
-floop-block
-floop-parallelize-all
-fgraphite-identity

It takes a LOT more time to compile and I can say that I doesn't give anything to user-experiece. The desktop feels the same. Maybe benchmarks could give some information about performance increase

In GCC 4.6 (and partly in 4.5) there was LTO, the link time optimizer. In 4.5 it was extremely unusable and now in 4.6 it's a bit better, but you shouldn't use it. IF it works, it works pretty well. But in Gentoo Forums many people said, that it'll compile fine and afterwards 20-30% of your applications segfault
The other new thing in GCC 4.6 is -Ofast. It's O3 + ffast-math. Should be just fine for a desktop I've always used O3 in Gentoo and never had problems.
-ffast-math should be okay, too. We will see.

EDIT: IMPORTANT:
PLEASE compile with Opengl and Opengl ES (it's possible, right?!, maybe it's also possible to switch between them. I've regocnized massive problems with nouveau and 2 outputs an my notebook (Geforce 9600m GT), when trying to add a 2nd screen via HDMI and krandrtray my notebook screen is flipped (bottom-top) but the mouse is still unflipped , no output on HDMI...

Just wanted to remind you: We need our bi-weekly update

benneque · 2011-04-08 18:15:29

No news are bad news
What's up with you and the repo?

Sorry, this was a hell of a week, much more work then I expected and an exam in school today. The repo will be updated during the weekend (unless something supernatural happens).

benneque · 2011-04-08 23:09:40

Oh okay, let's hope for a good mark

new networkmanager and knetworkmanager have arrived in Arch. I think it now uses system connection. I hope the next snapshot update will bring a few fixes for this (autoconnect doesn't really work)

Do you really need network manager though? Personally, I just use wicd and wicd-client-kde from AUR.

benneque · 2011-04-09 11:05:10

Maybe I don't "NEED" it, but it should be more practical for university. Cause there I need Cisco VPN and WLAN authentification using 802.1x (or something with a similiar name )
And NetworkManager is right now the standard network managing tool, used by all big distributions

benneque · 2011-04-11 19:32:02

kde-snapshots/kdesupport-phonon-gstreamer 4.6.42git20110305-1 -> 4.6.42git20110407-1

it says that my local version is newer than the update ?! why?

ProgDan · 2011-04-11 19:32:16

So, boys....the repo was finally updated. Sorry for the delay. The thruth is, that I got terribly drunk yesterday and I got that great idea that I could rewrite the script for checking out sources...It actually ended up pretty well, but took me lot of time today to make it really working...:) And of course I managed to break most of the other scripts last night, so I had to fix them too

In order to properly update you have to run pacman -Sy kde-snapshots. pacman -Syu won't work, beacause I made a typo in the previous version number and it's is actually bigger then the recent one (there's one extra zero in the previous snapshot git version number).

Ad NetworkManager: this will be probably quite disappointing for benneque: the 0.9 prerelease which recently hit official repos is incompatible with the stable 0.8 (some API changes) and KDE does not have support for it yet. I had to do some little hacking in order to make the KNetworkManager-0.8 built against the new NetworkManager and I seriously doubt it will really work...

For now I'm keeping the old packages in the repo, so if something will be broken (and I expect it to be, I just didn't run into any problem yet ), you can safely downgrade.

I'll try to make a new and better snapshot soon. I'm really sorry guys ...

benneque · 2011-04-11 19:51:40

No problem at all
We all know that especially after exams you have to drink beer for (examtime)^2 hours, to get back to life

NetworkManager kinda works with 0.9, mostly I have to reenable networking, but then it connects.

You didn't say anything about CFLAGS and OpenGL / ES

ProgDan · 2011-04-11 20:05:46

The CFLAGS on x86_64 are -march=x86-64 -mtune=generic -Ofast -pipe, on i686 it's -O2 instead of -Ofast, simply because I forgot to change it, but I set it already, so in the next snapshot will be there. OpenGL ES is still the same. As far as I know, turning on OpenGL when having OpenGL ES is not possible (????) but I didn't study it really, because I hadn't noticed your edit

benneque · 2011-04-11 20:21:40

Cool, so I'll have -Ofast
did you recognize any performance improvement?

I don't know about GL and ES at the same time.

Okay, now I have a problem with NM ...

When 0.9 update came I had to make all connections as system connections. So NM connects. The applet says "invalid state".

How can I downgrade that it works again?
