In any case, highmem support does not decrease speed much at all, and supposedly it's all what's needed for 2GB of RAM. For enabling full PAE support will, however, will reduce speed more as TLBs and/or caches need to be flushed to deal with the extra pages not mapped with the current process on ...

Today, I decided to give a try to the latest vanilla source (2.6.32-rc3).

During the kernel configuration I changed several things from the old configuration. Among them, I enabled:


Support for DMA Remapping Devices (EXPERIMENTAL)
Enable DMA Remapping Devices by default


I do not know if ...

yes, it is possible to use more than 2gb and yes and pcs are sold with more than 1gb.

That does not mean it is a smart choice. HP is selling pcs with 3gb - and dual channel memory controllers, it can't get more stupid like that.

If you want to access more than 1gb, you need highmem support ...

forget using more than 1gb on a 32bit machine?

because even if you could use the full 2gb - the slowdown makes it a questionable choice at best.

I am not quite following you. How is it possible 2GB RAM memory to slow down the system? Moreover, all the pcs that are sold are 32bit, and they have ...

Are you compiling your own kernel? Does it work with a precompiled kernel, say, the Gentoo livecd/livedvd?
Post your .config somewhere?

Yes, I am. I found an installation CD for Ubuntu 5.04, and the kernel recognized only 1GB RAM memory. I have not posted the .config file, I can post it here, do ...

Try running them at 400MHz. Sometimes the mobo itself can only handle a single stick of RAM at full speed.

I have a Phoenix BIOs, and it does not allow me to configure many things.

I boot in Windows XP ( which recognizes 2GB memory RAM) and I watch a movie over the internet. I had no problem ...

Have you run a multiple hour memory torture test with both modules installed?
Did it survive multi-day runtime session in the other Operating systems?

With RAM it is a good idea to have exactly the same module for both modules. Else you have to select very carefully to get a stable system ...

This is one thing that drives me crazy. I own a laptop with 1GB RAM ( at 533MHz), and I decided to install a second 1GB (533MHz) module. The Bios recognizes both modules and reports that I have 2048KB memory. Windows XP does the same thing. Memtest reports that my system has 2048KB memory RAM and ...

your emerge --info ?

Last night I decided to upgrade Qt from 4.2.2 to 4.5.1, and subsequently to update KDE to 4.2.3 from 4.2.2.

kdelibs-4.2.3 does not compile, and I get the following error:

/var/tmp/portage/kde-base/kdelibs-4.2.3/work/kdelibs-4.2.3/kdecore/util/klibloader.cpp:133: warning: ‘KPluginFactory* KLibrary ...

I managed to solve the problem with Solid by deleting the folder /usr/share/hal and then re-emerging hal.

The only thing that is left is to fix the problem with the network manager and ...

Take a look at one of my kernel seeds, with a focus on the SCSI settings. Those are of paramount importance with libata (SATA) drivers, as well as automounting CD's and USB devices. Also, USB drivers are best compiled into the kernel. Setting them as modules can lead to weird things like USB ports ...

In fact, you are quite right. As a further point of fact, declaring a USB drive or an optical drive in /etc/fstab will blind the hal/dbus system to the existence of said drive.

Adding one's user name to the plugdev, cdrw, cdrom, and usb groups in /etc/group is the final touch needed to make the ...

This is what I have in /etc/fstab:


# <fs> <mountpoint> <type> <opts> <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda3 /boot ext3 noauto,noatime 1 1
/dev/hda5 / reiserfs noatime 0 0
/dev/hda6 none swap sw 0 0
/dev/hda7 /tmp reiserfs defaults 0 0 ...

i removed the entries from my /etc/fstab and it works again.

Because I have a similar problem in KDE, which entries did you remove from the fstab?
Did you remove the entries that refer to the usb-stick, phone, etc? Did you also remove the entry that is for the cdrom?
After that, did you restart ...

Solid is fine - I have the same issue but I think I have figured out what is wrong. On kde.org there is a bug that says that baselayout-2 is using a different notation for the network interface listing than it did in version 1.

The result is that I even see the XML generated for the GUI on the ...

If you have upgraded qt from an earlier version ,i.e. 4.4 to 4.5 then you need to remerge kdelibs. Maybe there are some other kde programs that you need to reemerge, but start with kdelibs and hope for the best

I am in the plugdev group! Something else is wrong with the solid

It may state that in the KDE-4 Guide but that is not correct. IIRC, the kdeprefix flag does TWO things. One of the things is to keep different versions of KDE-4.x separated under /usr (as explained in the guide). But the other thing it does is let KDE-3.x keep the ~/.kde symlink so that a single ...

Yes I do confirm. Apparently the ebuild for the ati-drivers overrides the libraries that are used by the radeon(hd) driver. I do not know if there is a way to get around this problem.

My system is up to date and I have no clue what I missed. Or is this card just not (yet) supported? Any ideas?

Since your card is fairly new, I would suggest to use the radeonHD driver and not the radeon. This drivers is in the portage.

Until recently kde3 was logically always USE=kdeprefix even though this is a new use flag. So it is not a problem to USE=kdeprefix and have both kde3 and kde4 installed. All you have to do is to convert from USE=-kdeprefix to USE-kdeprefix is to unmerge everything that is KDE4 then change the ...

For me using kde3 and kde4 without kdeprefix gave me all sorts of weirdness.If you are doing same mistake get rid of kde3 and all ~/.kde* dirs and rebuild kde4 from scratch :idea:

Yes, I am not using the kdeprefix flag!
Unfortunately I cannot completely unemerge KDE 3.5.10. I need Kdevelop and ...

Do you have a recent kernel?

Have you tried revdep-rebuild, if you've updated some of the core packages like hal?

For me, updating the kernel solved some hal issues, the more recent the kernel, the better.

I'm guessing in the dark here, my setup is working fine.

Yes I do have a recent kernel ...
