   * VNC issues: Desktop environments that require hardware accelleration (3D desktop effects) are often too heavy to be used inside a virtual desktop (VNC, X2GO). See [[VNC desktop issues]] for details and workarounds.   * VNC issues: Desktop environments that require hardware accelleration (3D desktop effects) are often too heavy to be used inside a virtual desktop (VNC, X2GO). See [[VNC desktop issues]] for details and workarounds.
-  * X2GO has problems with some desktop environments that try to use "modern" features that are not there on the virtual desktop. For the moment, please use the ''XFCE'' or ''LXDE'' desktops that are known to work. 
   * An alternative to VNC and X2GO is [[XPRA]], a tool that can forward a single window or an entire desktop to a remote display.   * An alternative to VNC and X2GO is [[XPRA]], a tool that can forward a single window or an entire desktop to a remote display.
   * Gnome doesn't display //notification area// aka //system tray// icons any more by default. The fix is, to enable  the ''appindicator'' extension: open ''gnome-extentions-app'' (''Applications - Extensions'' in the menu) to do that. After that, the icons such as status icons of dropbox, zoom etc, will be in your top panel.   * Gnome doesn't display //notification area// aka //system tray// icons any more by default.

     * Note: in the previous OS versions, there was an extension named ''topicons plus''. If you had that enabled, you will have to enable the new extension now, and possibly remove references to the no longer existing extension.     * Note: in the previous OS versions, there was an extension named ''topicons plus''.

   * The ''clipit'' clipboard app that is a default part of Gnome, Cinnamon and MATE desktops, sometimes hangs, which blocks all cut, copy and paste actions. Exit the app by right-clicking on the icon (which looks like a clipboard), and choose the quit action. If this happens a lot to you, you might want to disable the app in your startup applications preferences. The app is only needed to maintain a clipboard history; without it, a single cut/copy and paste is still possible.    * The ''clipit'' clipboard app that is a default part of Gnome, Cinnamon and MATE desktops, sometimes hangs, which blocks all cut, copy and paste actions.

-  * Workarounds are in place for some software that was built with older versions of CFITSIO (GILDAS) and/or older GFortran (StarLink). When using these programs from within other programs, this workaround may be bypassed (eg, GILDAS software linked from within CASA). If you run into that issue, let us know so we can provide you with the necessary workaround. Eventually these issues are expected to be solved when new versions of these software packages are released or recompiled using current libraries. GILDAS also has a workaround to use python 3.10 in stead of the system default 3.11, with which it fails to compile.+  * Workarounds are in place for some software that was built with older versions of CFITSIO and/or older GFortran (StarLink).
