The administrator of the machine that was freezing-up suggested me that it
could be that the graphic card of the machine was flawed. I am thinking that
maybe the card was broken but the problem didn't show up with the older version
of X for mysterious reasons. Now he changed the graphic card and everything
seems to run fine. So maybe this is not a software problem? This is the old
graphic card (as of lspci -v):
01:00.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200 SE]
(Secondary) (rev 01)
Subsystem: ABIT Computer Corp. Unknown device 6190
Flags: bus master, 66MHz, medium devsel, latency 32
Memory at e0000000 (32-bit, prefetchable) [size=128M]
Memory at ff4e0000 (32-bit, non-prefetchable) [size=64K]
Capabilities: <access denied>
And this is the new one (as of lspci -v):
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon
7000/VE] (prog-if 00 [VGA])
Subsystem: ATI Technologies Inc Unknown device 1b8a
Flags: bus master, stepping, 66MHz, medium devsel, latency 32, IRQ 16
Memory at e8000000 (32-bit, prefetchable) [size=128M]
I/O ports at b800 [size=256]
Memory at ff4f0000 (32-bit, non-prefetchable) [size=64K]
Expansion ROM at ff4c0000 [disabled] [size=128K]
Capabilities: <access denied>
As you see they are not the same but this change seems to have fixed the
problem.
