the vesa driver should be okay, but it is a generic driver and therefore not always the best spot on driver.

for your card you should always use the "nv" driver.

with this and correct horizontal AND vertical figures, the display should be fine. what model is your Samsung LCD?

Yes! Changing "vesa" to "nv" in xorg.conf sorted Debian Stable.

It seems rather that the Linux install routines may not do too good a job of identifying the right video driver for the card that's installed. The simple diagnosis tool seems to be to find a distro that displays correctly (ie where the graphic screen is correctly aligned with the text one). Whichever driver that uses, use that one for all.

Job done! Off for a G&T!

The monitor is a prehistoric Samsung SyncMaster 570P TFT. I bought it for 50 about 5 years ago, so it doesn't owe me a lot. But it works well, and fits neatly into the corner where the Linux machine lives.

The xorg.conf files that I've been tweaking now have the full range of vertical and horizontal speeds for the monitor, and seem to be fine. Forcing 60.00 isn't needed with the "nv" driver.

The Debian Unstable (installed last week from scratch) has very little indeed in its xorg.conf, and nothing at all about video drivers. I may do some experimenting there in a few days' time.

Thanks for the help - I'm off now for that G&T!

good news then!

by the way, it is not uncommon for very little to appear in the xorg.conf files.

in the "early days", the X server was not too good at detecting video cards and drivers, thus much had to be specified.

nowadays, Xorg has matured out and most drivers will switch into performance modes automatically.

you can always "see" what X is doing by examining the /var/log/Xorg.0.log file created at X startup.

Indeed! Another step along the Linux learning road. It's easy once you know how, innit!

I'm still stunned by just how fast Slackware is on the old 600MHz Linux box - it boots in less than half the time the Windows machine takes - and that's a dual-core 3.2GHz job. When the day comes that XP Pro is no longer supported, I won't be changing to "son of Vista"!

Back to the G&T. Thanks for the tips!

yep mate. slack is fast, but then again so can be any linux.

the "heavier" distros like Debian, Mandrake, MEPIS, Red Hat, Ubuntu and so on tend to enable everything they have in terms of services and load drivers for hardware or options you do not have or use (IPV6 , floppy drives , software firewalls[iptables] etc re classic examples).

slack is thinner ... it only does what you tell it to ... the downside is that one requires more linux knowledge to configure slack.

but any distro, given effort , can be trimmed down. in all cases, they are all faster than widowze because the infrastructure and filesystems of linux are so far advanced and mature.

Arch linux is another good distro for "retired" hardware. Its based on Slackware and uses the same package system .. I personally think Arch linux is even faster than Slack. Slack is compiled for i486 architecture whereas Arch is for i686. I think the whole GUI/X experience on arch is swifter than slack but thats my own view having tried both on the same hardware and matched the configurations.
