With Synaptic package manager

Choose package (xserver-xorg-core), Package > Force version, choose version, click "Force version". click "Apply"


With Apt package manager

Searching packages

apt-cache show xserver-xorg-core

tells that there are:

xserver-xorg-core_1.3.0.0.dfsg-12ubuntu8.1_i386.deb Version: 2:1.3.0.0.dfsg-12ubuntu8.1
xserver-xorg-core_1.3.0.0.dfsg-12ubuntu8_i386.deb Version: 2:1.3.0.0.dfsg-12ubuntu8

Downgrading (forcing version)

Syntax is: apt-get install $package=version
so:

sudo apt-get install xserver-xorg-core=2:1.3.0.0.dfsg-12ubuntu8

Re: How to downgrade packages (forcing version)

Nice info!!

I do have to ask because I have seen a few posts here and there that a recent X update causes problems. What problems is it causing?

Re: How to downgrade packages (forcing version)

recent X update causes problems. What problems is it causing?

Certain programs (VLC, Boinc Manager, Filezilla...) don't work with xserver-xorg-core version: 2:1.3.0.0.dfsg-12ubuntu8.1.

With VLC (starting in the konsole) the error message was:

The program '.' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
(Details: serial 676 error_code 11 request_code 149 minor_code 5)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

Note
The latest xserver-xorg-core version is 2:1.3.0.0.dfsg-12ubuntu8.3. Trying... Seems to work (no errors with VLC). That was quick fix.

One can 'clean up' the resulting output from apt-cache show package and have just the version info you are looking for with this minor modification of the command:

apt-cache show package | grep Version:
