RE: [suse-linux-uk-schools] X servers for PC
I had a stab at using Mix a while ago, and had to add some fonts for my Logic Analyser, I remember that the documentation covers this - I think you place you 'new' fonts in the '/mix_win/bdf/misc/' directory and then change the FONTS.DIR file by including your font names and descriptions and increasing the 'count' at the start. i.e. FONTS.DIR starts 89 sm165.bdf -Misc-Fixed-Medium-R-Normal--14-120-75-75-M-80-ISO8859-1 lg165.bdf -Misc-Fixed-Medium-R-Normal--15-150-75-75-M-100-ISO8859-1 gb16.pcf -cclib-fixed-medium-r-normal--16-150-78-78-c-160-gb2312.1980-0 .... If you still have trouble email me directly and I'll dig a little deeper (and reboot the machine that I did it on back the M$ - currently running Linux for about the lasts 2 years). HOWEVER My current recommendation is to use VNC instead of X. It is free and has the advantage that it is stateless - when you M$ machine crashes the session on the Linux box remains running and you don't lose all your work. Hope this is helpful. Simon Wood
I also would recommend VNC over MIX, though my experience with MIX is somewhat out of date. VNC is very good if you have a fast network. On Thu, 23 Nov 2000, Simon Wood wrote:

However, if you want a (X|K|G)DM style login and full blown X server, try the Java-written GPL'd WeirdX - www.jcraft.com/weirdx Not tried it, but it looks like it works, which is a good thing IMHO :) J -- James Ogley, Network Manager, SuSE Linux Ltd - +44 (0) 20 8 387 4088 @ Work: ogley@suse.co.uk http://www.suse.co.uk @ Home: james@rubberturnip.org.uk http://www.rubberturnip.org.uk @ Mobile: riggwelter@sms.genie.co.uk ICQ: 57374251 Slashdot: riggwelter (84180) asylum-mud.org: Riggwelter "I lift up my eyes to the hills, from where does my help come?"

When did VNC start operating as an X server? How do you use it to do the equivalent of "xap -display <wsx>:0 &" for an arbitary number of workstations at the same time? AFAIK VNC simply enables remote display of a single X server, even if you could select which X server running 10's even 100's on a single machine is rather non trivial. -- Mark Evans St. Peter's CofE High School Phone: +44 1392 204764 X109 Fax: +44 1392 204763

It is a bit tricky but we have it operating that way. I am hoping I will have time to describe how to do so on "http://ict.felsted.org" Any of our machines (Arc, NC, Mac or PC) get an X login box when they run VNC, then they login and get the same KDE desktop they get from one of our diskless X terminals. -- Christopher Dawkins, Felsted School, Dunmow, Essex CM6 3JG 01371-820527 or 07798 636725 cchd@felsted.essex.sch.uk

At the moment its a single LINUX box to lots of (X) PC clients, so it sounds as if VNC is worth I try. I've only used VNC to remotely administer/monitor PC stations/servers. I'd be interested to know how the loading of multiple VNC sessions on the LINUX box compared to multiple X sessions. I had the feeling that VNC was quite demanding on processor activity to analyse and compress screen data...perhaps I'm wrong. X is no lightweight either generating a fair amount of net traffic (especially with multiple users running asteroids...if they learn how to access our LINUX box we let them play games for while.) Just picked up issue 3 of LINUX magazine. Excellent. Lots of reading and useful things to try. I hope the advertising doesn't increase at the expense of article space in the future. -- Alan Davies Head of Computing Birkenhead School

Are these PCs thick clients running an X application, or thin ones booting from (?)?

I'd use X where the client has X, and VNC for convenience when it doesn't, like we can't afford the X client for our Acorn kit. VNC works fine from clients that are 200MHz or over. At the server end it *is* a noticeable load, you are right, but it's worth it. You can run the VNC server on any spare machine too, it does not have to run on the xdm/applications server. -- Christopher Dawkins, Felsted School, Dunmow, Essex CM6 3JG 01371-820527 or 07798 636725 cchd@felsted.essex.sch.uk

Having been inspired by the above post, I downloaded VNC 3.3.3R2 which is the first version that supported the inetd option described above. It took me literally two minutes (ignoring typo's) to update /etc/services and /etc/inetd.conf, and -HUP the inetd deamon. Now I have X access from Win95 Pc's giving the XDM logon. It performs as well as my Starnet X-Win32 and if it carries on this well, I'll roll it out fuller. Once change I made to the instructions was to put '-query linux' instead of 'broadcast'.
