Re: i386 on AMD64 ?

Yes; what are you looking to install?

Re: i386 on AMD64 ?

i have a Dell Dimension C521 machine with AMD64 CPU, and i installed the latest Kubuntu 7.10 AMD64 version on it, but i'm encountering so many problems like software incompatibilities as well as hardware problems.

so i thought maybe i'll try and install the i386 version instead, hoping it'll solve the problems i have.

Re: i386 on AMD64 ?

I misunderstood you a little . . . I thought you were speaking of installing 32bit software in the 64bit version of Kubuntu. You shouldn't have any problems at all running a 32bit distro on your AMD64 processor

i'm encountering so many problems like software incompatibilities as well as hardware problems.

Really? I have found the rumors of 64-bit problems vastly outnumber the real problems. If I list all the real problems that I am aware of with 64-bit, here's my list:

1. Java Runtime Environment
2. Music Player at Rhapsody.com


that's it.

What problems are you attributing to the 64-bit OS?

Re: i386 on AMD64 ?

currently i have hardware problems (i believe that's the case) like mouse hangs so i have to restart Kubuntu in order to restore mouse operation, the system won't restart or shut down unless i force it with the power button (screen just goes black).

at least i solved the problem with Firefox and flash

Re: i386 on AMD64 ?

There are no mouse issues with 64-bit that I've ever heard of (I admit I haven't heard of every problem in the universe). Probably it is an issue with your xorg.conf file, vis-a-vis the mouse model that you are using, rather than a 64-bit issue. Is your mouse "special" in any way?


ALSO, when you think your system is "frozen", follow this guidance to avoid causing further problems with that power button:

That guide has rescued me numerous times - memorize it, especially if you're going to be experimenting with config files

Re: i386 on AMD64 ?

i saw another topic in this forum addressing the same problem - the mouse hangs. and it's the same manufacturer - Logitech. Mine is a standard mouse, nothing special about it.

Since i'm still a newbie to Linux, i don't know how to separate an X problem with true system hang. i will remember your tip about the shutdown (alt-SysReq). I also replaced the mouse with a different one - a USB Microsoft mouse.

Is your Logitech a USB or PS2 mouse?

Try this: log out and press Ctrl+Alt+F1 to switch to a terminal shell; exit KDM with the command

sudo /etc/init.d/kdm stop

Back up your current xorg.conf with the following command:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

Then, create a sample xorg.conf in your /home directory with the command

sudo Xorg -configure

It will contain important information you can add to your actual xorg.conf. Then, restart KDM with

sudo /etc/init.d/kdm start

Login, and edit your X.org config with Kate as root:

kdesudo kate /etc/X11/xorg.conf

Open the xorg.conf.new file you created in your /home directory, and add everything in the "Module" section to the "Module" section in your xorg.conf. If you don't have a "Module" section, create one.

Then, identify your USB mouse with

cat /proc/bus/input/devices

It should look something like

I: Bus=0003 Vendor=046d Product=c03f Version=0110
N: Name="Logitech USB-PS/2 Optical Mouse"
P: Phys=usb-0000:00:1d.0-2/input0
S: Sysfs=/class/input/input3
U: Uniq=
H: Handlers=mouse1 event2
B: EV=7
B: KEY=f0000 0 0 0 0 0 0 0 0
B: REL=103

Make note of the event* (in bold). Modify your mouse section in your xorg.conf to look like this:

Section "InputDevice"
Identifier "Configured Mouse"
Option "CorePointer"
Driver "evdev"
Option "Device" "/dev/input/event2"
EndSection

The "evdev" driver is specifically for use with USB mice. Replace "event2" with whatever you determined before, and leave the "Identifier" subsection the same (don't change it to "Configured Mouse" if it's anything different). Then, save and exit Kate, logout, and press Alt+E to restart your Xserver. If you get back to the login screen, CONGRATULATIONS!!! You successfully modified your xorg.conf Log back in and test your mouse; if it doesn't work as it should, check out this link with some more advanced USB mouse configurations. Try to find your model and make the appropriate changes.

Let us know how it goes.

Re: i386 on AMD64 ?

Thanks integr8e, i will give it a try.

In the mean time i searched the Internet and came up with this discovery : it seems that there is a series of Dell computers, all of them share the same problem: USB Mouse, and sometimes the keyboard too, halt. even unplugging and plugging again might not help. And this happen not only on xUbuntu but on other distro's of linux.

Dell have issued a BIOS update under Windows that suppose to handle that problem, but i cannot run it.

Also, Dell have created a Linux set of tools and updates for Firmware and BIOS , covering different models - but not for my model yet (Dimension C521). But i guess it's bound to come sometime.

Help came from an unexpected direction: i plugged a USB hub, not even powered externally, and plugged both keyboard and mouse to it. It Worked!! no more halts.

Heh heh heh ... so, I take it we're all in agreement there's nothing wrong with 64-bit Kubuntu, eh?
