So I did, I just installed Gentoo again and now I have the 64bit system. Wooooow. The system is SO MUCH more responsive now. It's not only because of memory - I just removed 2GB, and the system still was more responsive than with 2.7GB and 32bit OS. With 32bit, I was not able to play videos with mplayer when updatedb or emerge -p --depclean was running, now this is no problem, even without [io]nice being used. I do not know why this is - I did a setup quite similar to the existing system. make.conf is the same except for compiler flags, world file is nearly identical, kernel .config (2.6.33-tuxonice-r2) is identical except for some 64bit specific stuff, /home did not change. > > Check in your BIOS to see if you can reduce the amount your graphics > > card uses.

Thanks, I will have a look there. Found it. I can select 128, 256 or 512 MB, and set it to 128 MB. I hopped on my bike and went to the local hardware store in order to get another 4 GB of memory... but it was too expensive. Over a year ago, I paid 56 EUR for 4 GB, now I would have to pay 60 EUR for 2 GB. I'll wait. Now for the 64bit problems. There are few, it's working better than expected, but some things are weird. - At the first login into KDE4, four of my eight desktops were missing the background image. With every login, one came back, now I have them all. This issue fixed itself somehow. - My KDE4 is mostly in English now, not in German. kde-base/kde-l10n is installed, LINGUAS is set to "de". Some things are in German, though - some parts of the systemsettings application, for example. Oh, and after just another login - it's fixed. What's going on here? Maybe I should not write about other problems, and instead reboot a couple of times? - hibernate-ram does not work. When I resume, the display stays black. The numlock key ativates the LED, but I could not switch to a text cnosole. After Alt-SysRq-R, caps and scroll lock flash, I guess that means kernel panic. Happened for two times, I won't try this anymore soon. I see nothing in syslog. - Fortunately, hibernate (suspend to disk with tuxonice) seems to work. Did not try other yet, and the very first attempt stopped with the 'wacky driver' message. But the 2nd and 3rd attempt succeeded. This worked sometimes with the old system, but most of the times it aborted, I had to try about ten times for one success. And sometimes the system crashed, so I did not use this. Next morning update: Resume did not work, I got a 'LUKS killed' message. Oh no! I do not want to shut down the system every night again, I got used to hibernation. I'll ask on the tuxonice mailing list, hopefully this time someone can help me. BTW, I did change the graphics memory size after this, so this change is not the cause. - There is some font problem. There is only one application (media- tv/tvbrowser) in which the titles look bad, see the attachement (first time I do this on a mailing list, but it's small). That's no big problem, and I can activate antialiasing in tvbrowser, but I just wonder why this happens, this system should be quite identical. A diff of eix -I --only-names | grep font on both systems shows nothing. - x11-libs/xview (from the science overlay) does not build, it has -amd64 in KEYWORDS. I know about this already, and that I should not even bother to try compiling it anyway. But I need this libraries for stuff I am building. Linking 32bit libraries to applictions I build with a 64bit compiler cannot not work, right? Is there any easier solution than to chroot into a 32bit Linux? Which wouldn't be too bad, I still have my 32bit Gentoo, and I could just trim it down and keep it running. There were more problems, but they got solved while composing this mail. You wouldn't believe how often this happens to me, I start writing an email to this list, gather information that you might need to help, and solve the problem myself along this. Wonko
