| 06:39 | <MRH> hi I am using Linux Mint 17.3 cinnamon. Software rendering on the server side (due to older graphics card) however I am also getting software rendering on the terminal.
| |
| 06:40 | which is unuseably slow
| |
| 06:40 | anyone know if this is a cinnamon issue?
| |
| 06:41 | or should specifying a XSERVER=driver in lts.conf fix it?
| |
| 06:42 | truth has joined IRC (truth!~Tara@dslb-188-110-203-050.188.110.pools.vodafone-ip.de) | |
| 06:43 | <MRH> the intial LDM works fast as expected (like it is using the correct driver)
| |
| 06:44 | <truth> Has anyone been able to connect to an UEFI client so far?
| |
| 06:57 | <alkisg> MRH: thin or fat clients?
| |
| 06:57 | truth: yes
| |
| 06:57 | ricotz has joined IRC (ricotz!~ricotz@ubuntu/member/ricotz) | |
| 06:57 | <alkisg> Check the irclogs here for my notes
| |
| 06:57 | It's not very straightforward, a lot of the tools don't support it properly yet (e.g. ipxe)
| |
| 07:00 | <MRH> thin(ish) no local apps but nbd
| |
| 07:01 | <alkisg> MRH: 3d acceleration over the network doesn't work properly
| |
| 07:01 | So 3d environments are very slow
| |
| 07:01 | Either use 2d environment, or a fat ltsp session
| |
| 07:02 | 3d => I mean those that use opengl effects, a compositor etc. 2d are gnome-flashback, mate, lxde, xfce...
| |
| 07:02 | <MRH> ok
| |
| 07:02 | <alkisg> !ltsp-pnp
| |
| 07:02 | <ltsp`> ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 07:03 | <alkisg> ==> if your client has enough RAM to be a fat client
| |
| 07:03 | !uefi | echo truth:
| |
| 07:03 | <ltsp`> truth: uefi: To boot UEFI clients with LTSP, switch them to Legacy BIOS (CSM). If you can't, then use google translate on this one: http://alkisg.mysch.gr/steki/index.php?topic=6466.0
| |
| 07:04 | <alkisg> Hmm that's for the case when the client do have a hard disk though... I did manage pxe booting, but that was it was more compatible with many clients
| |
| 07:06 | UEFI works best with grub. ipxe can't load a vmlinuz kernel, only an .efi image (so for me it wasn't suitable, I wanted to boot a 32bit kernel). syslinux.efi had problems the last time I tried it, but I do want to try it again with the latest version.
| |
| 07:07 | Also dnsmasq doesn't support proxydhcp for uefi yet, you need a real dhcp server, not a proxy one
| |
| 07:12 | <truth> I already changed my ltsp-pnp setup to an isc-dhcp-server - unfortunately, ipxe didn't work.
| |
| 07:12 | Since my uefi-client has a hard disk I will now try to use grub.efi.
| |
| 07:12 | Is there any tutorial (link) how to do that?
| |
| 07:12 | <MRH> i remember something about a cinammon 2d mode
| |
| 07:14 | <alkisg> truth: ltsp-pnp + dnsmasq work fine with uefi, you just need to change one line, the proxydhcp one
| |
| 07:14 | I don't know of any tutorials other than the greek one I wrote, so try to use google translate on that one
| |
| 07:15 | <truth> Thanks, I will try this.
| |
| 07:15 | <alkisg> MRH: check /usr/share/xsessions, the available sessions are there
| |
| 07:22 | Fenuks has joined IRC (Fenuks!~Fenuks@91.192.173.88) | |
| 07:25 | <MRH> thinking about fat clients - can i use sshfs to mount home and other diretories
| |
| 07:25 | with ldm authentication
| |
| 07:26 | <alkisg> sshfs is the default, yes
| |
| 07:26 | <MRH> for a full OS type thing
| |
| 07:28 | <alkisg> Yes, that's what the ltsp-pnp page tutorial is about
| |
| 07:28 | !ltsp-pnp
| |
| 07:28 | <ltsp`> ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 07:41 | <MRH> ok i am going to mess around with fat clients a bit
| |
| 07:42 | <alkisg> MRH: what are your client specs? cpu/ram?
| |
| 07:43 | <MRH> modern celeron 4GB
| |
| 07:43 | i tested it as a standalone booting from HD first
| |
| 07:43 | <alkisg> Yup, you should definately boot them as fat clients
| |
| 07:44 | They'll run the same as if you were booting them from the HD
| |
| 07:44 | I.e. very fast
| |
| 07:44 | mikkel has joined IRC (mikkel!~mikkel@mail.dlvs.dk) | |
| 07:44 | <MRH> would you happen to have any pointeres to mounting other diretories via sshfs - not just /home
| |
| 07:44 | <alkisg> man lts.conf
| |
| 07:44 | !lts.conf
| |
| 07:44 | <ltsp`> lts.conf: (#1) http://manpages.ubuntu.com/lts.conf, or (#2) lts.conf manpage is available in the ltsp-docs package
| |
| 07:44 | <alkisg> Check for EXTRA_MOUNTS there
| |
| 07:44 | <MRH> ok gr8 it's in there
| |
| 07:44 | <alkisg> LOCAL_APPS_EXTRAMOUNTS
| |
| 07:47 | <MRH> yep just found it thanks
| |
| 07:48 | anything but NFS
| |
| 07:50 | <alkisg> NFS is more way more stable than SSHFS
| |
| 07:50 | But SSHFS is much easier and secure by default, that's why it's the default for ltsp
| |
| 07:50 | <MRH> idk i have always had difficulty and overhead trying to get NFS secure
| |
| 07:51 | especially considering users can jack in to a network point
| |
| 07:51 | i like the idea of sshfs
| |
| 07:53 | <alkisg> We've been using it for years here in 1000+ schools, it works OK except for hardlinks and cpu usage
| |
| 07:54 | truth has left IRC (truth!~Tara@dslb-188-110-203-050.188.110.pools.vodafone-ip.de) | |
| 07:55 | <MRH> i just tend to use it between servers, on their own nice little VLAN
| |
| 07:56 | but then i don;t have the experience of that many users
| |
| 07:56 | *hostile users
| |
| 07:56 | lol
| |
| 07:57 | <alkisg> For security it's better than nfs, sure
| |
| 07:59 | <MRH> anyway thanks alkisg i gtr and catch a bus! it's early here :)
