Message-ID: <506BA6BA.6040703@siddall.name> I mucked with the /etc/sysconfig/ltspdist to allow F16 then ran ltsp-build-client. The good news is the client appeared to build (got success message at the end despite some warnings along the way). The bad news is that the chroot wasn't really functional. I started by moving it to a suitable place (/opt/ltsp/i386-f16) and ran ltsp-update-kernels but no joy. First it complained about no pxelinux.0. Sure enough, nothing in the tftp directory. So I just copied the pxelinux* files from the EL6 chroot i386 directory and that got things further. The next problem was a kernel panic due to dracut not knowing what to do with "root=dhcp". Hmmmmm... so I ran chroot in /opt/ltsp/i386-f16 and then ran ltsp-rewrap-latest-kernel and got an error about missing dhclient. So I checked and sure enough no dhclient. That can't be right. So I installed it and re-ran ltsp-rewrap-latest-kernel. This time I only got some errors about "grep: /proc/modules: No such file or directory". Fair enough. So I re-ran ltsp-update-kernels but still no joy. This time the boot process hung for about 20 seconds and returned with "dracut Warning: unable to process initqueue" and then dropped into a shell. I am doing all this to try to get a working eGalax touchscreen which is borked in EL6 but worked fine in Fedora as far back as version 14. Sigh.

Message-ID: <1349883038.10327.21.camel@wc19.wc235> Jeff, It appears others have had quite a few probs getting the eGalaxTouch to work on various distros of Linux. Here is a good tutorial of how someone got the TouchScreen to work under Ubuntu. There are several steps of getting the Touch Screen to actually work but did end up working.It is quite a bit of leg work but may be worth a try under EL6/SL6 as well. I have been wanting to get a couple touch screens working under SL6 as well but haven't had time to monkey with this yet. I would have guessed these can be very quirky to actually get to work regardless of make/model.

On most any flash heavy site the TC really hangs and lags and fairly commonly will end up locking up. As long as it doesn't hit a flash site the performance is decent. Sometimes if it doesn't hard lock the Xserver restarts and the TC ends up back at the login screen were you are unable to use the keyboard/mouse. The TC has to be rebooted. I can not see any failures in the X logs or system logs. I have tried adding XSERVER= vesa # didn't make any difference. Tried XSERVER= via and the TC hangs at about before the login screen and stalls indefinitly. I did read a fairly old post were this TC would hang at boot due to the VIA Rhine integrated nic using ltsp 4.x ( I think?). Maybe this is a partial problem also? Anyone found a tweak for this unit? It is of course the VIA , C7? mobo?

I imagine this is in Firefox. As I recall, later versions of Firefox, from 3.0 on, talked to the X server such that they caused the X server to hold onto DRAM. In some cases, even 256MB wasn't quite enough. This is going back a few years, in the LTSP 4.2 days. Konqueror didn't seem to have that memory-hogging effect in X, but Firefox does. Any chance of giving this a shot in, say, Konqueror and seeing if it still happens? --TP On 10/25/2012 10:00 AM, Barry Cisna wrote: > Hello All, > > > LTSP 5.x > > Just bought an HP T5520 to use as an thin client.

I did try using Konqueror as the web browser.This did make web browser much faster when looking at flash heavy sites. My main objective was to test on RED5 sites which seems to really tank thin client performance. the prerformance was very nice using Konqueror,but strangely enough the HP T5530(I had reported this TC as being a T5520 by mistake, for completeness.) would still lock up when displaying the favorites within Konqueor for some reason. So I am not sure there may actually be more of an nic problem? I can not see any obvious errors within X.org or system logs. The TC will eventually hard lock or more often the XSERVER restarts and the TC winds up at the login screen but mouse and keyboard does not respond so the TC has to be rebooted. Thoughts: 1. This TC does take quite a while to bootup into the login screen from being powered off. Around 80-90 seconds. About twice the amount of time that other test TC's are taking. 2. I can see in the bootup sequence that this being a VIA Eden MOBO the VIA Padlock is being recognized and activeated/used. I am wondering if this add to overhead on the TC processing? 3. I do not have an second T5530 to test with and am wondering if their may be 'physical' problems with this particular TC. 4. I am going to try and update the bios on this TC to see if this may be a possible resolve. Slim chance I am guessing.

That solved a problem I was happening a while back with Dell OptiPlex GX1's (wouldn't PXE-boot, but would EtherBoot). Personally, I doubt that the VIA Padlock is the issue. It's possible, but that sounds like it'd be a horrible design flaw in the chip, and it's only used if there's software that tells the CPU to use the Padlock for the crypto stuff. --TP On 10/28/2012 01:48 PM, Barry R Cisna wrote: > Hello All, > > Thanks for the suggestions. > > I did try using Konqueror as the web browser.This did make web browser > much faster when looking at flash heavy sites.

Tomorrow I am going to try and do an bios update to this hummer. It looks like it has the original bios v1.00 , there is an v1.03. Digging a little deeper, looking in the bios it looks odd in that Flash memory = 64 MB,,,which looks kosher,,,but when looking at System memory = 112MB which doesn't look kosher! Seeing this either the memory seems wonky or the bios doesn't read the right memory. If I get psyhced up enough tomorrow to flash the bios I'll see what these readings are after the bios update.

I did get the bios flashed to version 1.03. This did not help the situation of the TC ineveatably locking up or more commonly the xserver restating and sending the TC back to the login screen. The TC does work fine and is very snappy on all websites and does in fact run Youtubes fine.Once you hit an flash site or such as Facebook the mouse gets very 'springy' and short hangs then recovers usually, and will eventually xserver restart. Long story short,,I had seen mixed specs and thought this TC did have laptop ram slot in it,It does have soldered on ram. 128 MB simply isn't enough for the running kernels these days in my opinion. Hope this may help someone in a decision of trying to use the HP T5530 as an TC for ltsp 5.x.

Unfortunately this TC has soldered on memory.No open slots for adding memory. When I looked up before buying this off of Ebay of course at least memory vendor showed that this TC had 200 pin laptop memory.that was my intention to put at least 512 MB ram into. I am guessing if this had 512 MB ram it would a very nice TC to use with ltsp 5.x. The mouse simply gets "springy" at times,,then catches up,,,,but,it also on RED5 enabled sites especially will end up with x crashing/restarting and ends up back at a login screen were you have to reboot the TC to get the mouse/ keyboard functional again. I have found it is best to test a potential TC on RED5 hosted sites as it seems these sites really tank a TC due to the inherent flash stuff that RED5 is hanged off of. For example just trying to torture the TC it appears most of the time even Facebook is fine,,and then the TC runs out of memory from flash,and pictures and hangs then catches up. Again Youtube(s) videos run fine,,and without buffer on this TC 100 % of the time. In regards to the nbd swap block,from what I can tell the ltsp 5.x (default) automagically is setting up each TC with this feature. Can someone else on the list here confirm this? I may be seeing something wrong on this? I do see like 65000 enabling ndb swap during bootup.If I am wrong this would be a good deal to try 'Im sure.... Take Care, Barry
