Could not open default font 'fixed'
by Bertram Franz 16 Oct '23

16 Oct '23

Hi, I still see https://github.com/ArcticaProject/nx-libs/issues/84 on my OpenSuse, with x2goserver-x2goagent: 3.5.99.24 (from x2goserver-x2goagent-4.1.0.7-0.0x2go1.0.git20230823.1996.heuler.x86_64 = latest nightly build). Is there anything I can do to analyze that further? Is there a workaround to get the server to run? Thanks, Bertram

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/

Questions about x2gokdrive licensing
by Orion Poplawski 29 Sep '23

29 Sep '23

I'm trying to package x2gokdrive for Fedora, but running into some questions/issues with the licensing: 1 - There is no license file in the released tarball 2 - The debian/copyright file in the git repo states that the license is GPL-2+ except for testscripts/* at GPL-2. However, licensecheck reports: ./x2gokdrive.c: Historical Permission Notice and Disclaimer - sell variant ./x2gokdrive.h: GNU General Public License v3.0 or later ./x2gokdrivecursor.c: GNU General Public License v3.0 or later ./x2gokdriveinit.c: GNU General Public License v3.0 or later ./x2gokdrivelog.h: Historical Permission Notice and Disclaimer - sell variant ./x2gokdriveremote.c: GNU General Public License v3.0 or later ./x2gokdriveremote.h: GNU General Public License v3.0 or later ./x2gokdriveselection.c: GNU General Public License v3.0 or later ./x2gokdriveselection.h: GNU General Public License v3.0 or later 3 - This code is combined with the Xorg server code which is under the MIT license. This is quite a mess. Any chance this could be cleaned up? Thank you. -- Orion Poplawski he/him/his - surely the least important thing about me 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

Next Events/Upcoming X2Go and orca e.V. Sponsorship Drive - Tomorrow, 2023-09-05
by Stefan Baur 04 Sep '23

04 Sep '23

Dear $ALL, X2Go will be present at LinuxDay.AT <https://www.linuxday.at/> in Dornbirn, Austria on Saturday, September 30th, and also at the IT-Kongress <https://it-kongress.com/> in Neu-Ulm, Germany, on Thursday, November 9th, 2023. At both events, we will have a booth where we will demo X2Go-KDrive, as well as the HTML5Client beta and X2Go's integration into the latest Remmina client. At LinuxDay.AT, there will also be a talk with a live demo of how you can run a small X2GoServer instance in the Google Cloud, for free, using Tor (The Onion Router) to log in. The talk at IT-Kongress will be a behind-the-scenes look regarding the customer-driven development that led to the creation of X2Go-KDrive. (Note that both talks will be in German, but our booth staff at both events is fluent in German as well as in English.) If you're planning to attend and/or are in the area, feel free to stop by and say hi! Both events are free, though IT-Kongress requires registration. We are trying to cover the costs for our two volunteers/orca e.V. members (Mihai and me) via orca e.V., the registered association that X2Go belongs to, but for that, we will need your help in the form of donations*. You can find our donation pages here: X2Go (English): <https://www.betterplace.org/en/projects/111056?wirwunder=235> X2Go (German): <https://www.betterplace.org/de/projects/111056?wirwunder=235> orca e.V. (English): <https://www.betterplace.org/en/projects/111057?wirwunder=235> orca e.V. (German): <https://www.betterplace.org/de/projects/111057?wirwunder=235> It would be really cool if you could send some $$$/€€€/£££/¥¥¥ our way, so we can keep advocating for X2Go and free remote desktop/remote application projects in general. We can accept donations via PayPal, Credit Card, Direct Debit, giropay/paydirect and wire transfer. Best of all, donations towards X2Go and orca are usually tax deductible for German tax subjects. Note that there is a special sponsorship drive sponsored by our funding platform, betterplace.org: Non-recurring donations up to 100 Euro made on Tuesday, 2023-09-05 (starting 00:00 CEST) will receive 20% on top directly from betterplace.org. Larger donations will receive 20 Euro on top instead. This offer is only valid until a funding pool of 12.000 Euro is depleted. So the earlier you donate on this particular day, the higher the chance that your donation will receive the bonus from betterplace. Kind Regards, Stefan Baur (with his X2Go Event Planner hat on) *If times are rough for you and you can't afford to donate, don't feel bad! You can also help us by forwarding this announcement to whomever you seem fit - e.g. your local Linux user group, your social media followers, etc. If you're on Twitter, you can retweet and like the following to help: <https://twitter.com/farbenstau/status/1698651187577282841> (English) <https://twitter.com/farbenstau/status/1698651871773086181> (German) Feel free to copy the text and links of these Tweets to any social media platform that you are using. -- 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

x2gokdrive build question
by Orion Poplawski 17 Jul '23

17 Jul '23

I'm working on packaging x2gokdrive for Fedora and I'm seeing the following in the configure log for the xorg x11 server: configure: WARNING: *********************************************** Neither HAL nor udev backend will be enabled. Input device hotplugging will not be available! *********************************************** Is this of any concern for kdrive? I do see that there is an explicit: --disable-config-hal \ --disable-config-udev \ so probably not. But it *seems* like input device hotplugging might be useful just judging by the name. But perhaps not since this is on the server end of things?
