X2goclient fullscreen does not adjust screen resolution after update
by christoffer krakou 08 Jan '24

08 Jan '24

Hello list I have recently upgraded the following packages Upgrade package libnx-x11 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package libxcomp3 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package libxcompext3 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package libxcompshad3 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package nxagent 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package nxproxy 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package x2goagent 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 On my Ubuntu 12.04 server. Now, when i connect using the x2goclient, it works well when i select a resolution and run it in a window, but when i select fullscreen, the resolution is 1920 X 1200, no matter the resolution on the client monitor. This results in the Unity controls being unusable. Before the upgrades, there were no trouble. Is anyone else experiencing the same? -- Venlig Hilsen / Best Regards Christoffer Krakou Fleten.net APS

x2gokdrive memory corruption
by Orion Poplawski 09 Oct '23

09 Oct '23

I'm seeing x2gokdrive abort with "malloc(): unsorted double linked list corrupted", which indicates some memory corruption. Is anyone else seeing this? Has anyone tried running x2gokdrive under valgrind? Any tips for doing that? -- Orion Poplawski IT Systems Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

loginctl 'enable-linger' causes systemd --user to respawn on boot
by Montjoy, Robert (montjoy) 28 Sep '23

28 Sep '23

Hi. At one time "loginctl enable-linger" was added to the x2gostartagent to make sure the systemd did not kill the x2go process on disconnect. This has had the probably undesired affect of having systemd --user username being executed on boot for every x2go user. At the last boot about 70 processes (one for systemd and one for pam) were spawned. This is probably not what we want. Is there a better way to handle the systemd termination issue? Should something like systemd-run --scope --user x2goagent ..... be used instead? Or can x2go cleanup this entry on termination? Maybe have x2gocleansessions do it? Note: I will probably cleanup /var/lib/systemd/linger on boot by executing rm -f /var/lib/systemd/linger/* but that it is more of a "hammer" approach than anything else. Thanks in advance. Rob
