Replace 64bit X with 32bit X on FC4 x86_64

rosholm · 10-20-2005, 03:24 PM

I have a clean FC4 x86_64 installation.
Unfortunately there are no 64bit linux drivers for my graphics card - trust me!

Therefore I would like to run 32bit X on my 64bit installation, because the manufacturer has told me that this should work (in theory - never tried in practice) with the 32bit driver available.

Now, my questions are as follows:
1. Can I expect 64bit X-applications to run properly in 32bit X?
2. Which 64bit packages do I need to replace with 32bit packages to have a 32bit X running?
I expected the operation to be done by a number of yum commands like:
yum remove <X-package>
yum install <X-package>.i386

I would like to replace as few packages as possible.
Maybe 'yum remove xorg-x11' and 'yum install xorg-x11.i386' will do the job by letting yum resolve all dependencies?

I better ask before I do something messy.

For your information I have listed the output from 'yum list installed X*' below.

Code:

# yum list installed X*

I have no idea if it'll work, but it seems plausible. I'd be very interested to know if it does or doesn't.

In order to use yum to get the i386 stuff, you'll have to create repo files for base-i386 and updates-i386. If you don't, yum won't be able to find all the i386 packages you need. (The x86_64 repos don't contain the entire universe of 32-bit packages.)

Code:

# gedit /etc/yum.repos.d/base-i386.repo

Edit the file to contain this.

Code:

[base-i386]
name=base-i386
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/4/i386/os/
gpgcheck=1
enabled=0

Now add a repo for the i386 updates packages.

Code:

# gedit /etc/yum.repos.d/updates-i386.repo

Edit it to contain this.

Code:

[updates-i386]
name=updates-i386
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/updates/4/i386
gpgcheck=1
enabled=0

To use these repos, you'll need to add the --enablerepo flag to your yum command, like this.

Code:

# yum --enablerepo=base-i386 install *x11*.i386
# yum --enablerepo=updates-i386 update *x11*.i386
