#StackBounty: #16.04 #remote-desktop #rdesktop rdesktop gives ERROR: Failed to open display:

Bounty: 50

I have a .bash_aliases file with several aliases which I use to connect to Windows machines. The aliases are set up like this:

rdesktop -d domain -u username -p password -k fr-be -g 1920x1024 -T Customer-SupportPC -a 24 IP

Yesterday the connection was working fine, today the connection gives me following error:

ERROR: Failed to open display:

SSH sessions are no problem, it’s only a problem with rdesktop to a Windows server. X11 forwarding is set to yes in /etc/ssh/sshd_config

#StackBounty: #16.04 #intel-graphics Cursor getting stuck in launcher

Bounty: 50

It’s a weird issue. The cursor gets stuck in place but still moves so that if I click I click on what I aimed to but the cursor is not where it should be. It only happens in the launcher. I tried this to no avail.

#StackBounty: #16.04 #drivers #nvidia #graphics #screen Screen Rendering Issues

Bounty: 50

I have a laptop with a NVIDIA Corporation GM108M [GeForce 940MX] (rev a2) graphics card, using NVIDIA Driver Version: 381.22.

Recently I have been having issues with the screen rendering on all programs. For instance, when typing into a web test box (like this) the characters are not getting displayed until either a delay or losing focus.
Also if I double click on a word (to highlight it) the edges goes blue (to show word is selected) but the middle part under the mouse cursor does not.

As the example below, double click on the word highlight and only the left couple of characters have highlighted, the area under the mouse is uneffected.

#StackBounty: #16.04 #wireless Ubuntu 16.04 on Surface Book – Wireless internet disconnects randomly until restart

Bounty: 50

I have dual-booted Ubuntu 16.04.3 LTS and Windows 10 on my Surface Book, and on the Windows side I have no issues with the wireless internet at my work office. On my Ubuntu partition, it seems that sometimes when I switch access points, my wireless internet gets disconnected and is not able to connect to the same network or any other network until I restart my computer. This issue also occurs even when I haven’t switched wireless access points. It’s not consistent at all.

I’ve tried the solutions posted here, here, and here without any luck. This is a rather frustrating issue because the restart disrupts my workflow, as you can imagine.

I’ve looked at several other questions and tried their solutions without any luck. Any help would be greatly appreciated. Here is a link to my wireless-info.txt: https://ufile.io/abkfd

#StackBounty: #16.04 #mouse Can't click my mouse a few minutes after boot on 16.04

Bounty: 100

Right after startup, my mouse works perfectly fine (sometimes takes a few seconds to register, but good after that). However, a few minutes into using Ubuntu (has happened in both 16.04 and 14.04), the left click stops working for part of the screen.

Here’s what I can do when this happens:

  • Move the mouse anywhere on the screen.
  • Keyboard works perfectly fine.
  • Hover over items in the dock to the left (my list of applications).
    • Sometimes even this doesn’t work, though.
  • Click on items in the dock to the left and have the application launch.
    • Sometimes this fails too.
  • Hover and click on items in the top menu bar for the application.
  • Sometimes right clicks will be registered in the terminal, as well as being able to select text in the terminal.

Here’s what I cannot do when this happens:

  • Interact with any application on the main screen (click on links, switch to a new window, etc.)
  • Select text in the active window.
  • Right click in the active window.
  • Scroll using the scroll wheel.

Things I’ve tried to resolve the issue (but none work):

  • Check the power settings for my USB devices (they’re all on).
  • Check to make sure the mouse (Corsair M65) works on Windows (it does).
  • Plug the mouse directly into the PC instead of my keyboard’s USB port (no change).
  • Checked my system log with tail -f /var/log/syslog (nothing shows up).
  • Listen for the mouse click event with xev (keyboard events show up, but mouse events do not).

The only thing that I can do to get my mouse back is to reboot.

I don’t notice a trend of which this happens, but I did notice it happen one time after launching the terminal, not sure if that was related or not.

Any ideas on what I should do besides a clean Ubuntu install?

EDIT: Found something that fixes it (temporarily)! Thanks to this answer, I have discovered that hitting ALT + CTRL + F5 and then ALT + F7 gives me full control over my mouse (until I lose it again). Better than nothing, but a permanent solution would be greatly appreciated!
