| |
| 15:00 | I'm using ubuntu 12.04
| |
| 15:00 | and I want to print from firefox
| |
| 15:00 | and I have all the network printers configured at the server...

| 16:04 | Phantomas has joined IRC (Phantomas!~Phantomas@ubuntu/member/phantomas) | |
| 16:05 | <ltspuser_05> to increase the performance of the firefox I changed it to run as a localapp
| |
| 16:05 | but when we use a browser we need to open some docs and do many things...
| |
| 16:05 | do I need to install all the other programs as localapps too??
| |
| 16:06 | like a pdf reader, open office??
| |
| 16:06 | or is there a way to use the ones on the server
| |
| 16:06 | ?

| |
| 16:15 | <gvy> pong
| |
| 16:15 | IIRC you have to, yes
| |
| 16:16 | significant part of the problem is "where's the data"
| |
| 16:16 | and "what are the possible handlers"
| |
| 16:20 | <ltspuser_05> all the things are on the server...
| |
| 16:20 | I only have the firefox app running localy...

| 16:44 | <||cw> ltspuser_87: that is one drawback of local firefox.
| |
| 16:44 | if you're thin clients are fast enough to run all that anyway, ight as reconfig for fat client
| |
| 16:44 | ight/might/
| |
| 16:47 | <ltspuser_87> so, I have to install all the other apps that firefox need right?

| 17:48 | <mip5> Morning Folks - I've got a widescreen display, but the image is "stretched." There are no options to change the display settings when logged into the client. Any thoughts? I haven't specified anything special about these clients in lts.conf - maybe I need to.
| |
| 17:55 | <||cw> mip5: vga or dvi? the drivers probably aren't auto detecting properly, common with vga. you can set the res in the lts.conf
| |
| 17:56 | komunista has left IRC (komunista!~slavko@adsl-195-168-234-074.dynamic.nextra.sk, Ping timeout: 264 seconds) | |
| 17:59 | <mip5> vga - yeah, it's not detecting monitors (or at least, I get nothing back after selecting that). How would I specify it in lts.conf? I've got 12 clients with these monitors, and about 25 others with standard monitors.
| |
| 18:01 | <mgariepy> ||cw, remote apps support is working: http://www.stgraber.org/2010/12/06/announcing-ldm-2-2-and-ltsp-5-2-5/
| |
| 18:03 | ||cw, basicly all you need to do is to set REMOTE_APPS=True and you are done, local firefox or chromium/chrome will call a wrapper script to launch the app on the application server

| 19:07 | <mip5> Silly question - how can I determine the video card in my thin client? I'm trying to set the display options in lts.conf so that I can use the widescreen without the image being stretched.

| 19:56 | <mip5> Okay - I've been able to enter the [MAC address] in lts.conf to have a particular machine boot differently (eg, SCREEN_02=shell). However, I can't seem to get it to read my X_MODE_0=1366x768 resolution. Any ideas?

| 19:57 | <||cw> mip5: you might need modelines then
| |
| 19:57 | <mip5> llcw: can you give me more details?
| |
| 19:58 | <||cw> I've only done it on native linux installs
| |
| 19:58 | is it not possible to use dvi?
| |
| 19:58 | or the screen doens't have it?
| |
| 19:58 | <mip5> No - I had originally spec'd dvi monitors, but they were out of stock, and the school bought vga instead
| |
| 20:06 | <||cw> I seen to recall a couple sites that have modeline generators
| |
| 20:08 | <mip5> okay - I'll keep hunting around. It seems like I'm missing something basic...
| |
| 20:11 | <ltspuser_44> Hi to all, a simple question, can i compile the client image for ARM processor ??
| |
| 20:12 | My server is Ubuntu 12.04.1 LTS
| |
| 20:26 | PhoenixSTF has left IRC (PhoenixSTF!~rudi@193.136.242.251, Quit: Leaving) | |
| 20:29 | <||cw> ltspuser_44: "compile" is the wrong word, it builds from existing already compiled packages. any arch that ubuntu 12.04 supports should be buildable

| 20:33 | <ltspuser_44> Hi, thanks for the answer, i have tried some --arch parameters without success, for example --arch armel or --arch armv7 or armeabi. I have succesfully created the image for i386. What type of arguments i need to use ?

| 20:35 | <ltspuser_44> Ahh ok, i have understood. I need to see if "12.04" is compatible with ARM processor. Otherwise i need to find the last version for ARM.
| |
| 20:36 | JesseC has joined IRC (JesseC!JesseC@wsip-98-175-20-126.br.br.cox.net) | |
| 20:45 | <||cw> right
| |
| 20:47 | <mip5> llcw: If I could get the proper modeline, would I put that in a stanza for my thin client [mac address]?
| |
| 20:49 | <||cw> yes, but I'm not sure on the specifics of how

| 21:08 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 21:13 | <mip5> I tried adding X_MODE_0 = 1280x768 below the [mac address] stanza for this machine, but it doesn't appear to do anything. If I specify the resolution, must I specify everything else, eg, modeline?
| |
| 21:14 | <vagrantc> shouldn't have to
| |
| 21:14 | although you probably should use XRANDR_MODE_0 if your card supports xrandr
| |
| 21:14 | in fact, specifying the modeline is actually broken
| |
| 21:16 | <mip5> ok - trying it now....

| 21:16 | Phantomas1 is now known as Phantomas | |
| 21:18 | <mip5> strangeness! Top 3/4 of screen are horizontal lines of the login page (4 overlapping copies), and the bottom 1/4 are vertical colored lines
| |
| 21:21 | tried XRANDR_MODE_0 = 1366x768, and got a different, but non-usable patter of horizontal mostly b&w lines, and color pattern in bottom 1/4 page
| |
| 21:22 | <vagrantc> typing xrandr will give you a list of modes supported by your videocard/monitor
| |
| 21:22 | if you can get any modes working well enough to use
| |
| 21:23 | <mip5> so - where should I type that - enable SCREEN_02=shell in lts.conf?
| |
| 21:23 | <vagrantc> mip5: from an xterm on the thin client
| |
| 21:23 | <mip5> ok
| |
| 21:23 | <vagrantc> mip5: or can you get no useable modes at all?
| |
| 21:24 | <mip5> at this point - no useable modes (but I'll change my lts.conf). I've got a widescreen monitor, and am trying to get the image less "stetched" - default res os 1024x768
| |
| 21:25 | <vagrantc> but with 1024x768, you could use it enough to run xrandr from an xterm?
| |
| 21:25 | <mip5> yes - i'll do that as soon as I can get back into the box
| |
| 21:26 | <vagrantc> you might be able to run it from the a shell prompt by setting the correct DISPLAY and XAUTHORITY variables.
| |
| 21:26 | <mip5> I think the problem is that I'm using vga, and can't seem to detect the monitor. hopefully running xrandr will get me there.
| |
| 21:26 | <vagrantc> it'll tell you what it thinks will work
| |
| 21:27 | <mip5> xrandr says: Failed to get size of gamma for output default. Screen 0: min 640x480, current 1024x768, maximum 1024x768

| 21:33 | <mip5> my last line of output discusses the audo device - nothing about kernel driver
| |
| 21:34 | <alkisg> Do you have anything like XSERVER=vesa etc in your lts.conf?
| |
| 21:34 | <mip5> Sorry - there is this before audio driver: Subsystem: Intell Corp Device [8086:1999]
| |
| 21:35 | no
| |

| |
| 21:36 | http://lists.freedesktop.org/archives/dri-devel/2012-January/018076.html ==> kernel 3.3: gma500: Add support for Cedarview
| |
| 21:39 | I.e. it's possible that using a very recent distro/version for your chroot, like e.g. ubuntu quantal, might make your clients graphics work much better (faster + correct aspect ratio)
| |
| 21:41 | <mip5> Could I run 12.04 as my main OS, and have a chroot that's 12.10? Do you recommend moving everything to 12.10?
| |
| 21:42 | <alkisg> Sure you could do that
| |
| 21:42 | <mip5> Could you tell me how to build that chroot?
| |
| 21:43 | <alkisg> I'm not sure yet that this will fix the problem... you'd need to verify that your graphics card is only supported properly in 3.3+ kernels before switching to 12.10 or other distros
| |
| 21:43 | I think ltsp-build-client --dist quantal or something likethat
| |
| 21:43 | <mip5> okay - I do see lots of stuff regarding VESA in my Xorg.7.log

| 22:08 | <mip5> Well, I'll have to wait on this until tomorrow. I am not sure how to get a different driver into my chroot environment. Specifying different XRANDR_MODE_0 = only seems to work for 1024x 768, which is what's working on the default settings anyway. Thanks for your help though.

| 22:48 | <mint__> Hey Gang - I was trying to get my thin client to display 1366x768 resolution using xrandr, but failed.
| |
| 22:48 | I booted to a usb live disk of Mint14, and the 3.5 kernel does include drivers that work with the graphics card in this client
| |
| 22:50 | vagrantc: alkisg was helping me regarding this display issue. Turns out drivers in Mint14 (3.5 kernel) work with this Intel graphics card.
| |
| 22:54 | <vagrantc> mint__: you might be able to just pull a backported kernel into your chroot...
| |
| 22:55 | <mint__> not sure how to do that - add backports to sources.list in chroot, and apt-get install?

| 22:58 | <mint__> vagrantc: lsmod shows a gma500_gfx - looks like it might be the one
| |
| 23:13 | Gotta run now - thanks for your help.
