To build this package a few files are generated with the Lemon Parser Generator which isn’t really available. I’m contacting upstream regarding the possibility of including the generated files in the tarball, or eventually if that fails, I’ll probably need to include lemon.c, hand compile it and hack scons build to use the local binary to generate those files.

The screenshots have a tiny glitch on an icon, this is mainly because I haven’t rebuilt the icon cache when I took them. I look forward to explore the possibility of having such a great tool available for openSUSE 12.1.

UPDATE: I’ve made available a small test package on home:ketheriel:gpick (needs some work before submitting to factory) which should be working. Any testing/feedback will be most welcomed. Also enabled builds for Fedora 14, since I believe this package isn’t available for Fedora.

For some time I wanted to check out GNOME3 and gnome-shell… My current chipset is ATI M92 RV710 and while the thermal performance with the proprietary driver is somewhat what I expect, the open source radeon driver does overheat my laptop a lot compared to flgrx. For the time being, fglrx isn’t really a choice because it just borgs the ‘activities’ bar on top… And until ATI fixes their driver, there’s no other choice than running with the standard radeon drm driver, which does provide a very pleasant experience with GNOME3 / gnome-shell.

For all that matters, KMS is to be enabled, period, full stop. And from this point… we have two options regarding power management:

1. Dynamic Frequency switching (not really working for me);
2. Profile based frequency switching (does provide what I need);

For all that matters regarding ‘profile based frequency switching’ we have 5 profiles available:

• “default” uses the default clocks and does not change the power state. This is the default behavior.
• “auto” selects between “mid” and “high” power states based on the whether the system is on battery power or not. The “low” power state are selected when the monitors are in the dpms off state.
• “low” forces the gpu to be in the low power state all the time. Note that “low” can cause display problems on some laptops; this is why auto only uses “low” when displays are off.
• “mid” forces the gpu to be in the “mid” power state all the time. The “low” power state is selected when the monitors are in the dpms off state.
• “high” forces the gpu to be in the “high” power state all the time. The “low” power state is selected when the monitors are in the dpms off state.

Now, what I did might not be an option to everyone, but for sure it does provide a nice solution for my problem… So be mindful of that… this is a personal preference based on the fact that I don’t require intensive GPU usage, neither I run intensive GPU requiring applications within GNOME3/gnome-shell (I have a normal openSUSE 11.4 with GNOME 2.32.x with fglrx dual boot config for those apps).

The first thing we might want to do is to switch to profile based frequency switching… how do we this? As root:

[code] echo profile > /sys/class/drm/card0/device/power_method[/code]

Now we have to pick one of those 5 profiles… and since I’ve already stated… I want the ‘low’ profile since I don’t really do much intensive GPU work…

[code] echo low > /sys/class/drm/card0/device/power_profile[/code]

Now… you might want to check out the different profiles and the different clocks used… this can be done through:

[code] cat /sys/kernel/debug/dri/0/radeon_pm_info[/code]

and will report something like this:

[code]linux-331w:~ # cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 680000 kHz
current engine clock: 299530 kHz
default memory clock: 800000 kHz
current memory clock: 249750 kHz
voltage: 900 mV
PCIE lanes: 16[/code]

This one is using the ‘low’ profile… Feel free to test stuff around and find which one better answers your needs… Also there’s far more that can be done… I hope this helps ATI users with DRM driver to bring out the best of your system and improves your GNOME3 / gnome-shell experience, at so that you can run it with good thermal performance without fglrx.

Some brief updates about the ongoing work towards bringing Ayatana Project software into openSUSE:

1. Software Updates

Canonical recently released a batch of updates which bring new functionality (Indicators seem to respond faster now) and very nice improvements, some of them contributed by down-streamers. From my humble experience I would risk to claim that Canonical is doing an excellent job as an upstreamer. I’ve updated all packages to the latest versions. This allowed to remove some patches.

2. Unity

Unity is now one step closer. For Unity I’ve started to package Compiz git snapshots from the correct branches pointed by Unity documentation. This brought something new to me, cmake. I’ve done this very slowly, reading some docs meanwhile about cmake. My packaging around Compiz is mainly based on OBS X11:Compiz repository, so pretty much all the credits should be for the original project Packagers which done an awesome job. Currently I’m missing only 3 packages to test Unity. Recently with kernel and mesa updates some issues around ATI hardware seem to have fixed for openSUSE Factory users, which enabled in my case FireGL, therefore I can test properly Unity now and check for the integration into openSUSE.

Unity by default uses the Ayatana’s Indicators, and if they are not present, it will fallback to GNOME’s applets. This is very nice and I’m thankful Canonical made it this way. This brings non-Ubuntu users the Unity experience at almost no trouble, since there isn’t actually much patching required to implement Unity.

3. GNOME:Ayatana Repository

GNOME:Ayatana Repository will be populated during the next two weeks with the latest changes and will provide for the time being the Ayatana’s Indicators and Unity. I am currently working around libappindicator stack and it’s Indicators. Currently I’m testing the patches required on the GTK+ stack and this is pretty much the last barrier before going into #STAGE2, polishing and populating GNOME:Ayatana.

It’s not decided yet what packages are going to present on Factory. My wish is to push only Unity into Factory and it’s dependencies, this might not happen for 11.4 as I’m not sure about the freeze schedules and it might be too late already, but since we’re depending on Compiz upstream, we’ll see what happens. Even if Unity isn’t going to be available on Factory, I’m sure we can use KIWI or SUSE Studio to release a small openSUSE Unity Spin.

I’ve also decided that I (typo: previously would) wouldn’t like to see Unity available by openSUSE before the official release from Ubuntu, for which I wish all the success.

Since the very early start that I’ve been using pkg-config as much as I can. According to some information that I collected previously, this would be great for cross-distribution build. Depending on the time and work done, I might make the necessary modifications and enable cross-distribution building on this project, thus, making it available for other RPM distributions supported by OBS. This will require a bit of testing before, so it will be work to be done after 11.4 is released and during it’s lifecycle. Maybe by the time of openSUSE 12 gets released, we will have this project also available for other RPM based distributions. I have no knowledge on Debian packaging, but Ubuntu ships this software and Debian probably has it also available so… that won’t be a problem.

4. Artwork

I am providing on GNOME:Ayatana Ubuntu’s Light Themes (Ambiance and Radiance) and offering a patched version of Metacity that renders those themes perfectly. I’m not changing the original colors from the themes or modifying them in any way. So they might be a bit more of orange and not green.

I’ve contacted some people to ask if they would be willing to donate some artwork to make a small package with Wallpapers, some have answered yes, so I will make a small package with a couple of wallpapers for the traditional resolutions and distribute it alongside with this software as optional as always.

5. GTK2, GTK3 and QT

Implementation of GTK3 will be done within the next days, as I am also considering enabling QT support for KDE users (Indicators only for now).

That’s pretty much the result of the last days of work… more news to come in the nearby future.
