| * We also have the interpreters of python 3.8, 3.10 and 3.11 installed, for compatibility and in case you need them for your own projects or virtualenvs. These are the bare interpreters, we do not provide a complete stack of modules for these older versions. | * We also have the interpreters of python 3.8, 3.10 and 3.11 installed, for compatibility and in case you need them for your own projects or virtualenvs. These are the bare interpreters, we do not provide a complete stack of modules for these older versions. |

| * Also, all compatibility with 32-bit executables was dropped some time ago. Not surprising, since the last 32-bit machines were bought by our institute in 2006.

| * TeX package ''psfig'', which has been obsolete for a long time, has recently been removed. Converting documents to newer packages such as ''graphics'' or ''graphicx'' is recommended, and is usually easy. | |

| * 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).

| * Gnome 3. Gnome 3 is a completely different desktop design, which makes the desktop look and behave a bit like a Tablet PC. Some people may like it, but if you don't, "Mate" is available as an alternative, to give you the experience of good old Gnome 2, or "Cinnamon", for a more desktop-like version of the new Gnome, or try "Gnome Classic". \\ [[gnome|More on Gnome 3]] | * Gnome.

| * Gnome applications: in every new release, more Gnome applications are rewritten in the style of the Gnome 3 desktop. This means: a separate application menu, displayed Mac-style in the top bar on the Gnome desktop, or under the application icon in other desktops, the most important actions displayed as buttons, and everything else in a menu at the top right in the application window. \\ See [[desktop applications]] for a table listing alternatives, in case you cannot get used to the new look. | * Gnome applications: in every new release, more Gnome applications are rewritten in the style of the Gnome 3 desktop.

| * The command ''pmount'' can be used to mount removable media (cdrom,dvd,usb-disks) from the commandline. E.g.: ''pmount /dev/cdrom'' mounts the cd/dvd as /media/cdrom. | |
