Regards, Florian Philipp One of my friends uses ATI video card both on desktop and laptop machines and he told me recently that the free driver for ATI video chips ( http://xorg.freedesktop.org/wiki/ati ) is very good nowadays and is being actively developed. He also said that the performance of his video card with open-source driver in different modes is almost the same as with the proprietary driver. I just don't remember the exact video card model, unfortunately. And according to this article: http://www.phoronix.com/scan.php?page=news_itempx=MTA3NDE AMD releases the code for some newer chips as well. Which gives more chance for the new hardware to work good with GNU/Linux. Regards, Vladimir - v...@ukr.net

[gentoo-user] cannot set an icon theme for the kde apps
Hello, list. I just installed gentoo for the first time. I am using openbox wm and some kde apps within it (krusader, for example). I installed the systemsettings package(4.8.3) to configure the kde apps. The problem is that i cannot set an icon theme for the kde apps. There is no entry for the icon theme configuration in the systemsettings (please see http://www.image-share.com/ijpg-1633-222.html as an example). Changing the name of icon theme in the config file (~/.kde4/share/config/kdeglobals) gives nothing. So, the question is: how to change icon theme in the kde apps?

[…] I don't want to pay a premium price for a bleeding-edge device which wb available at a more normal price a few months later. Those two statements are a bit contradicting. Generally, I wouldn’t buy an i7. First, those high-end components tend to be comparatively more expensive than their smaller siblings (regarding bang for the buck). Okay, it’s a quad with HT instead of “just a quad” (oh my, the times we live in), but secondly, if it’s *mostly* a desktop and occasionally performance-critical, I think it is also a waste of power. More power means more heat means more fan noise. I wb buying it from the local store (Canada Computers), not on-line. Does anyone have thoughts or advice ? A friend of mine built a new machine recently. I too am planning on doing this once I got the bucks (hopefully) in a few months. So we picked components together, based on recommendations of an “efficient home-brew PC” article in computer magazine c’t. We know that Intel is more expensive, but also less power-hungry and known to work excellent both with Linux and with other components. And my friend believes that the Intel graphics drivers are still superior from a FOSS standpoint (he had an ATI in his old system). Using the comprehensive Wikipedia articles on Ivy Bridge¹ and LGA1155², we decided for the biggest i5 (3570K, ~220€), as it has the bigger of the two HD Graphics chips (external Graphics were not on the shoping list). This new baby built GCC in 12 minutes and a bit. First he wanted an Intel board, but because those don’t have VGA anymore, he went for Gigagybe. He was building a big tower ATX system, and so chose the Z77 (around 100€). I, however, am planning for something more modest, a cute mATX system with medium power. Right now I’m planning on a B75 board. It has all *I* need and is considerably cheaper (70€). I think I may also take the smaller i5 that comes with HD4000, the 3475S, which is around 25€ cheaper. But even then, it is still a beast when compared to my Core 2 Duo laptop which has to run permanently throttled due to its ageing heat spreader. This is a Sandy Bridge CPU. I normally don't recommend the Ivy Bridge ones because they run hotter, so changing the clock multipliers isn't as fun as with Sandy Bridge. Yeah, according to the aforementioned Wikipedia article¹, they changed the heat spreader material inside. However, the 2550K you recommended has a TDP of almost 100W, whereas Ivy Bridge maxes at 77W. How much those figues are to be taken as real-world values is of course something else. A nice improvement of Ivy Bridge in my view is its integrated USB3 controller, which, according to some tests, is considerably better than the patched-on solutions of Sandy Bridge boards. And if you don’t want a dedicated graphics card but still want some GPU power, that’s of course another plus for Ivy. Hm... perhaps one can use the best of both worlds and use a Sandy CPU ond an Ivy board? The other way around would work with a BIOS upgrade.

[gentoo-user] Need a clue about merging logical volumes/groups with lvm2
I know there are a few lvm2 experts lurking here :) I have a 500gig disk that is split roughly in half between two volume groups, each containing four physical volumes, and each vg is formatted into an ext4 filesystem of roughly 250GB. What I plan to do is merge the two volume groups into one, containing one big ext4 filesystem, which will contain all of the files currently on the disk. Can this be done without copying one of the existing ext4 filesystems to a separate drive first, and then copying it back after extending the remaining vg/filesystem? (One filesystem has 24GB free and the other has 25GB free.) I'm expecting a no but I'd like to be wrong :)

(One filesystem has 24GB free and the other has 25GB free.) I'm expecting a no but I'd like to be wrong :) I think you are right. But if you had more free space, it might be possible. So your physical volumes are about 63 G each. If you free that much space on one filesystem, reduce the file system, then reduce the LV, you can use pvmove to move stuff from one PV you want to empty to the others. When done, you can remove the now empty PV from the VG with vgreduce. Then use vgextend to add the PV to the other VG. Extend the LV of that VG and enlarge the file system, copy stuff from the other FS over until you can free another PV. And so on. But copying all stuff of one VG to another location would be much easier. And less error-prone. Wonko
[gentoo-user] Printer isn't working. Help, please!
Evening, Experts! My printer isn't printing. More precisely, when in CUPS 1.5.2 (localhost:631), CUPS fails to find the printer. When I click on Find New Printers it comes back with Available Printers - No Printers Found.. My system has been like this since I converted back from mdev to udev. Though I have just built Linux 3.3.8 in the hope that a new kernel build would help. ;-(. Help would be most appreciated. TIA! -- Alan Mackenzie (Nuremberg, Germany).

Their graphics chips aren't nearly as good, though. AMD radeon open source drivers are getting better with every kernel. Apparently there was a huge performance increase with 3.5 alone. They are catching up and as long as you don't have something brand new the support is pretty good (and apparently even this is getting better, too). Funny enough, there are some things I've actually had run faster using radeon than fglrx, mostly with wine games. But the radeon driver still does not have full support and even some things will simply not work with them.
