#StackBounty: #18.04 #sound #volume-control Ubuntu 18.04 : Volume control on system doesn't change volume but volume control on vid…

Bounty: 100

So my title describes the problem pretty much entirely. I can’t get the volume to change using the system volume control via my keyboard or through the volume drag bar accessed through the “Activities” bar on the top of the screen.

But I can get it to mute both of those ways. Additionally I’ve been able to control volume through the video player volume controls (youtube/netflix etc) that are available to me while watching videos.

How do I get the system volume control working again?

#StackBounty: #18.04 #sound #headphones #headset One side of headset / headphone does not work in Ubuntu 18.04.1

Bounty: 50

When I connect my headset to my laptop running on Ubuntu 18.04.1, sound can only be heard from the right side. I have tried testing the speaker in the sound settings, which shows the same result. The headset works correctly when connected to other devices. I also checked with another headphone, which also had the same issue.

I have tried suggestions from other answers, such as this and this, but they did not work. The following is the output from alsamixer:

enter image description here

So it appears that the bars for both channels are set to full. I also checked in the sound settings that the sound balance is at the centre.

How can I find the source of the problem, and resolve it?

Thank you.

It shows the Modem but I can not find it on the network section, even after unmount the ‘ZTE USB SCSI CD-ROM (2.31)’ device from the disk. What should I do? Or, Can anyone tell me the process of installing modem handler like Windows OS ?

#StackBounty: #nvidia #18.04 #graphics #ssh #xorg How to enable "AllowIndirectGLX" on Ubuntu 18.04 with Nvidia (1050Ti)

Bounty: 50

Following scenario: I like to a run an opengl application from a remote cli only server (with a matrox graphics card) through “ssh -X”. My local machine is running Ubuntu 18.04 with Nvidia graphics. I’ve google’d around and found, that I need to enable “AllowIndirectGLX” locally. Unfortunately I’ve not found how to do this the right way.

There seem to be two possibilities:
1. Adding ‘”AllowIndirectGLX” = “on”‘ to some xorg.conf.
2. Adding “+iglx” as a launch parameter to Xorg command.

Problems with this: There is no “xorg.conf” under “/etc/X11”. The only file that comes near this is “/usr/share/X11/xorg.conf.d/10-nvidia.conf”. For solution 2 my best guess is “/usr/bin/Xorg”. But maybe I need to set this for the GDM configuration?

I would like to avoid endless trail and error sessions. Hopefully you guys can help out!

Thank you in advance!

#StackBounty: #dual-boot #18.04 #mouse #touchpad Touchpad not working in Acer Predator Helios 300

Bounty: 50

My touchpad is not working in Ubuntu 18.04. I am using dual boot system and touchpad is working fine in windows. I have read several answers on how to fix this issue, but unfortunately none of them works. I have updated my kernel too.

When I change touchpad in BIOS settings to “basic” from “advanced”, then touchpad in Windows is affected.

If you need any more information about my system please put them in comments.
