Procedure from Ubuntu forum:Had the same problem and fixed it in a strange way.Go to alsamixer (just type alsamixer in terminal)Make sure your sound card is the one selected by pressing F6 which will show you a list for the available sound cards. Select yours! ...If you're not sure try them all. It's not dangerous ;)alsamixer...I noticed that I had many volume bars having their right part lower than their left part. (in this picture you see only one). So I just lowered all their volumes to zero and back up again and they became even. (to "navigate" just use your arrow keys. Right and left to select the bar, up and down to lower/raise the volume).link: https://askubuntu.com/questions/496607/no-sound-from-right-speakers== doublecommander ==DoubleCommander is a cross platform two window file manager.

Double Commander is not included by default in Ubuntu’s 11.04 repositories, but I included instructions on how to install it from a PPA. Double Commander offers both GTK and Qt interfaces (so the first one blends well in GNOME while I recommend the second one for KDE), comes with a twin-panel style and includes a big number of configuration options.sudo add-apt-repository ppa:alexx2000/doublecmdsudo apt-get updatesudo apt-get install doublecmd-gtk # for the GTK (GNOME) versionsudo apt-get install doublecmd-qt # for the Qt (KDE) interface== Display applet in Settings causes system freeze ==Display applet in Settings causes system freeze* https://github.com/linuxmint/Cinnamon/issues/6224Workaround: Use arandr tool to modify display. Downside: changes made here will reset after system sleep or restart.Problem persists in the beta release of Mint 18.2 Sonya Cinnamon version.----Bad news: This driver is no longer maintained so it's very unlikely this will get fixed.Good news: This driver is only useful for really old Intel GPUs (10 year old and more... the likes of i800x, i915, i965) and it is not recommended for recent Intel GPUs. Instead, it is recommended to use modesetting, not only to avoid this freeze issue, but also to get better performance.Anyhow, there are two solutions to this problem:Solution 1 - Recommended for people with modern Intel GPUs (2007 and newer)Remove the Intel driver to use modesetting instead:apt remove xserver-xorg-video-intelAnd then reboot the computer.Solution 2 - Recommended for people with old Intel GPUs (i965, i915, i8xx..etc)Disable VSync:echo CLUTTER_VBLANK=none >> ~/.profileAnd then log out.----debugging tools journalctl -p3 -b | cat cat /var/log/Xorg.0.log mhwd -li cat /etc/X11/xorg.conf.d/*.conf== GTK+ File Chooser Dialog ==[[GTK+ File Chooser Dialog]]GIMP (GTK+ 2)GTK+ file chooserFor GTK+ dialog, the location bar will not appear while viewing "Recently Used" in the file chooser.
