Ubuntu 18.04.2 LTS problems after automatic suspend, vast file of errors on screen no functions

Hi to all I am new here and a novice Ubuntu user having escaped the clutches of Microsoft at last! I am getting a fairly regular issue with my system if left for a few hours after going into automatic suspend. I either have no functions available via keyboard or mouse or otherwise get a screen full of process information which I am unable to copy. Any help or suggestions gratefully received! N.B. I am really pleased with the setup other than this glitch, only way I can think of sharing the screen is to take picture and try to post it but it is not ideal as there are pages of info. Many thanks in advance.

Lubuntu 18.04.2 – reset audio driver?

I have multiple displays hooked up to multiple GPUs and one of the connections is via HDMI to a switch that is connected to an HDTV, so audio throughput (via HDMI) is required. I accomplished this with paprefs and the creation of a virtual audio device that combines both 3.5mm analog and digital sound so that both the speakers and HDTV have audio. The problem is that the switch (used because I need to connect more HDMI devices to the HDTV than it has HDMI ports) sometimes disconnects and this sometimes causes the TV to lose the audio, though not the video. A reboot fixes this, but I was wondering if there was a way to “reset” (meaning reload, while KEEPING the sound settings) the audio driver without having to wait for the whole PC to reboot.

Audio not working in Ubuntu 18.04.2 LTS

I have Ubuntu 18.04.2 LTS installed. And I was able to use audio devices on my laptop a week ago. And today,it turned out that my audio devices are not working. Even the sound toggle and volume control bar is disabled.

enter image description here

Here is output of

lspci -v | grep Audio

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05) Subsystem: Sony Corporation 5 Series/3400 Series Chipset High Definition Audio

Tried reinstalling pulseaudio, rebooting the laptop but didnt worked.

Ubuntu 18.04.2 LTS boots slow

I have a ThinkPad, t480s, and it is supported by Ubuntu pretty well. Upgrading from Ubuntu 16 to Ubuntu 18.04 brought me mainly advantages, but also 1 big disanvatage: boot time increased. I use password to login and while I boot my pc, it takes like ~5 to load on this ubuntu purple screen. This was not the case with Ubuntu 16. Same thing happens also on some HP laptops.

Here is the output from systemd-analyze blame :

Trying to install Ubuntu 18.04.2 dual boot, it works for the first time, as soon as I reboot once it won’t boot anymore, “PCIe Bus” error

I’m attempting to to install Ubuntu 18.04.2 in a desktop computer with a Windows. I downloaded it and made a bootable USB stick. I then chose the simplest install options and allocated 32 GB of my SSD. Ubuntu then loaded correctly, but, as soon as I rebooted it once, when trying to boot again, it just logs a lot of lines in a white font with a black screen behind. Those lines say:

pcieport 0000:00:1d.2: PCIe Bus Error: Security=Corrected, type=Physical Layer, (Receiver ID) 

Reinstalling Ubuntu works again only once. As soon as I reboot it, I can’t boot again.
