x2go performance again
by Stefan Seidel 31 Jan '17

31 Jan '17

Hi, some time ago I inquired about peoples experience with x2go in a LAN environment. I have now built a TCE live system (TFTP-only, no NFS) and a new Jessie server and I am still not very satisfied. I tried almost all available options. Here is the setup: 1GBit/s LAN on both sides Host: AMD 4.4GHz 8-core CPU with 32GB RAM Client: Pentium D 2.8GHz, 1GB RAM, nVidia 6200 with 2 screens@1200x1600 I tested MATE desktop with Firefox 51 (tried XRender on/off) and Chromium 55. I usually set the browser to fill half of the screen, that mean roughly the same number of pixels as a Full-HD (1920x1080) screen. I usually open https://www.heise.de and scroll up and down a bit. nopack: almost the best of it all, responsiveness good, Chrome and Firefox without XRender laggy rfb-hextile/tight: better for small screen updates, worse for large screen updates, scrolling in Firefox with XRender active is *very* smooth rdp: almost identical to rfb adaptive: middle ground, everything is laggy but at least there's always the same amount of lag for small and big screen updates. Unacceptable though because almost all text has JPEG artifacts no matter whether the quality is set to 1, 7 or 9. Graphics like Munin graphs are really ugly. 16m-png: good quality, mostly lag-free except Chrome and Firefox when XRender is off, becomes very unresponsive with lots of screen updates 16m-jpeg: artifacts, speed like adaptive I believe nopack or rfb would give better performance if it was possible to circumvent going through SSH. I have set SSH to use arcfour (this is a trusted, isolated LAN) and performance has been slightly better. Is there any way of making the initial authentication and startup through SSH but then having the NX connection going directly to the client? That would save a lot of processing power! (I'm thinking similar to the "tunnel" feature for sound.) Regards, Stefan

OpenSuse

The source of the stty turned out to be in my own .bashrc, don't know how I managed to miss it or why it did not stop x2go from working on any other distribution (centos 6/7, SL 6/7, debian, mint, ubuntu), all of those distributions worked in spite of it. Also don't know why .bashrc was sourced when my normal login shell is ksh. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Transport endpoint is not connected? RE: Shared Folders, from Windows to Debian8
by KARL A. WOELFER 26 Jan '17

Thank you again Stefan for the more detailed instructions, I am ~closer. I selected automount for one folder on my WIndows client, "Benchmarking" >From X2go, on the Debian 8 server side I see : lrwxrwxrwx 1 kw* kw* 25 Jan 25 12:49 media -> /tmp/.x2go-kw*/media kw*@chdd:~/media$ cd disk kw*@chdd:~/media/disk$ ls -alrt ls: cannot access _mnt_home_kw*_.x2go_ssh_key.Ja4672__cygdrive_C_Users_KARLWO1_DOCUME1_BENCHM1: Transport endpoint is not connected total 8 d????????? ? ? ? ? ? _mnt_home_kw*_.x2go_ssh_key.Ja4672__cygdrive_C_Users_KARLWO1_DOCUME1_BENCHM1 (??? above are the Unix file attributes) This directory entry then goes away. kw*@chdd:~/media/disk$ ls -alrt /tmp/.x2go-kw*/media/disk total 8 drwx------ 5 kw* kw* 4096 Jan 25 13:03 .. drwx------ 2 kw* kw* 4096 Jan 25 13:04 . Transport endpoint not connected doesn't sound good, but I don't know what to do with this information. I also don't know the significance of the _mnt_home_kw*_.x2go_ssh_key.Ja4672__ which precedes the _cygdrive_ name that we are expecting. Is there something more I should have installed/running (Cygwin for example) on my Windows 7 laptop? X2go client is version 4.0.5.0 (Qt 4.8.6) Thanks for any and all help with this, - Karl ________________________________ De : Stefan Baur <x2go-ml-1(a)baur-itcs.de> Envoyé : mercredi 25 janvier 2017 11:08 À : x2go-user(a)lists.x2go.org Objet : Re: [X2Go-User] Shared Folders, from Windows to Debian8 Am 24.01.2017 um 22:49 schrieb KARL A.

Windows folder > I am sharing on the Linux side? Well, if you don't check the automount box - nowhere until you mount them? How you mount them manually depends on what checkboxes you checked under Options/Settings/General. 1a) If you set X2GoClient to minimize into the system tray, then you right-click that icon, select the session name, then "Share folder ...". 1b) If, instead, you have the X2GoClient window on your screen even with an active connection, click on the small folder icon, that's the left of the three icons "Folder, Pause, Power". >From there, the steps are the same again for both variants. 2) Click the name of the share in the window that has opened now 3) Click the "share" button. If you either performed these steps or had the automount box checked, your mountpoint will be somewhere under ~/media/disk/, with a name starting with _cygdrive_. > My Windows laptop has a single-user authentication, whereas we use LDAP > on Linux, is this a potential problem? I do not believe so. The mount is performed by FUSE through a tunneled SSH connection, with the Cygwin SSHD spawning on your client, so it's your server connecting back to the client, using a temporary SSH key pair, so there's no exchange of your individual password involved. I'll try to come up with a HowTo with a few screenshots, but at present, my only Windows machine that has a US-English GUI is busy spinning its hourglass over the Windows Update window ... which is not surprising, as this was the first time since Mid-2014 that I powered it up. -Stefan -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243

Shared Folders?
by KARL A. WOELFER 25 Jan '17

25 Jan '17

I am not able to get the basic Shared Folder capability to run. Debian 7 Linux OS on client and server, X2go V 4.0.3.0, and XFCE Desktop. Is there something fundamental preventing this from working? Thanks in advance, - KarlW

X2GO and Plasma5
by alfons 24 Jan '17

24 Jan '17

Time ago i was very happy with x2go to connect several users, simultaneously, to a KDE session server. Since KDE became plasma5 x2go give up running. I read "problems with libraries". Actually there is no alternative like this. May we expect x2go is going to run with plasma5 in the future? Thanks in advanced Regards *Alfons Sanchez Ferrer*

OpenSuse Leap 42
by Robert Dinse 22 Jan '17

22 Jan '17

With OpenSuse Leap 42 as the destination machine, Ubuntu 16.04.1 LTS as the originating machine: I can login with x2go as root fine, but if I try as any other user I get standard input inappropriate ioctl for device. I can ssh with the same user and get no error. I have made sure I don't have mesg or stty in my .profile and .kshrc (I am using ksh as the login shell) and if I did it would also cause the same issue with ssh login. Can anybody tell me what else to check? -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Keyboard problems: Ctrl-Alt-Left works, but not Ctrl-Alt-Right
by John Stoffel 20 Jan '17

20 Jan '17

Hi all, I'm running x2go on CentOS 7.x using the following packages: x2goclient-4.0.1.4-1.el6.x86_64 x2goserver-4.0.1.20-1.el6.x86_64 And when I run the server on my desktop, and then the client so I can connect to the screen I've setup, I have some minor keyboard problems. I can use Ctrl-Alt-Left to move inside the Full Screen x2go session to another panel. But I cannot move to the right at all, nor does running xev inside the x2go session show me hitting those keys. Just to note, I'm not running x2go and shadowing my :0 display (which might be better?) because I want to lock my session when I leave the office, and pick it up at home without worrying about people seeing my display while I'm away. In any case, my setxkbmap INSIDE my x2go session shows: > setxkbmap -query rules: base model: pc104 layout: us options: ctrl:nocaps While outside it shows: > setxkbmap -query rules: evdev model: pc104 layout: us options: ctrl:nocaps I'm actually using a tenkeyless CODE keyboard, but I don't think that makes much difference here. Using the 'gnome-keybinding-properties' I have the "Switch to workspace on the (left|right) of the current workspace" setup to be Ctrl+Alt+Left or Ctrl+Alt+Right from what I see. Using 'xev' both inside and outside of the x2go client I see different keycodes for my arrow keys. Outside, in the standard CentOS 7.x Gnome desktop, I see keycoded 113 (left) and 114 (right), but inside x2go I see 100 (left) and 102 (right) so there's some mapping going on somewhere which isn't getting through properly. For example, inside X2go session, when I press and release the left arrow key, I get: KeyPress event, serial 37, synthetic NO, window 0x7400001, root 0x6e, subw 0x0, time 3164346691, (107,75), root:(109,832), state 0x0, keycode 100 (keysym 0xff51, Left), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 37, synthetic NO, window 0x7400001, root 0x6e, subw 0x0, time 3164346811, (107,75), root:(109,832), state 0x0, keycode 100 (keysym 0xff51, Left), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False So I'm wondering a couple of things. 1. If I edit my ~/.x2go/config/config/keystrokes.cfg file, does it get re-read automatically or do I have to stop and restart the x2goclient or the entire x2goserver session to have my changes take effect? 2. Has anyone else seen this issue and have suggestions on how I can maybe get around this? Thanks, John P.S. I do also have various nx* packages installed, would these be interferring? > rpm -qa | grep nx | sort freenx-0.7.3-9.4.el6.centos.x86_64 libNX_X11-3.5.0.32-3.el6.x86_64 libNX_Xcomposite-3.5.0.32-3.el6.x86_64 libNX_Xdamage-3.5.0.32-3.el6.x86_64 libNX_Xdmcp-3.5.0.32-3.el6.x86_64 libNX_Xext-3.5.0.32-3.el6.x86_64 libNX_Xfixes-3.5.0.32-3.el6.x86_64 libNX_Xinerama-3.5.0.32-3.el6.x86_64 libNX_Xpm-3.5.0.32-3.el6.x86_64 libNX_Xrandr-3.5.0.32-3.el6.x86_64 libNX_Xrender-3.5.0.32-3.el6.x86_64 libNX_Xtst-3.5.0.32-3.el6.x86_64 nxagent-3.5.0.32-3.el6.x86_64 nxclient-3.5.0-7.x86_64 nx-libs-3.5.0.32-3.el6.x86_64 nxproxy-3.5.0.32-3.el6.x86_64 Thanks!
