Questions[aspire](ubuntu)

I'm trying to install Ubuntu 18.04 (18.04.1 will try tomorrow) onto Acer Aspire A315-41-R8XR. I have unpacked iso file to my flash and booted to grub successfully, but when I select "Try Ubuntu", I just get black screen and that's all. I have also tried to select "Install Ubuntu", but I get many errors:

^{Google: watchdog: BUG: soft lockup - CPU#1 stuck for 22s! [migration/1:15]}

Windows 8.1 works fine, although it was already on the disk from another notebook, so, I think, it is not a power supply problem.

I've seen many such posts in the internet. It seems that people lost Ubuntu on Ryzen with Vega...

How to fix? May be use newer kernel? How to do it?

I've recently installed Ubuntu 12.04 and I love it. However I have one problem- I am unable to shutdown or reboot properly.

When I shutdown my laptop (Acer Aspire 5560) it hangs on the 5 dots and stays there.

When I reboot my laptop it does shutdown but when it boots back up it stay's on the Purple screen (no logo what so ever)

Thing's I've I'd to stop this:

• sudo service network-manager stop before shutdown - nothing

• Adding some lines the the GRUB file - nothing

• installed other Ubuntu versions - nothing
• sudo shutdown -h now - nothing

and some more.

At the moment I see a black screen in front of me with the text

 Asking all remaining processes to terminate [OK]

And the 5 dots with only the last one orange.

On other tries I got this thing:

modem-manager:could not get the system bus......

I first had Ubuntu dual boot Windows. And then it worked fine. However after a fresh install of Ubuntu alone I got this.

I've tried do undo this but not able to get it disabled. My sound settings need to be redone every boot up as well, but asking that question as well would get neg. feedback.

How to get microphone to work on acer aspire one 722

I'm having difficulty in adjusting brightness on my Acer Aspire 4740:

• Screen 14.1-inch glossy LED-backlit, 1366x768 res
• CPU Intel Core i5-430M 2.26-GHz
• RAM 1GB DDR3
• HDD 320GB
• Graphics Intel GMA HD

Im using Ubuntu 10.10 . I do not have this problem in Ubuntu 10.04 , but this problem occur in Ubuntu 10.10 . I can't decrease or increase my brightness even in Compiz.

I have an Acer Aspire 1551-5448 Netbook that is running Ubuntu 10.10 64bit Desktop.

I'm loving making the move to Ubuntu but my major stopping point is waking the laptop from a suspend/hibernate mode. When waking the computer I get a black screen. I understand this is most likely a hardware issue and would like to note that I am using the ATI drivers.

Also, I checked the /var/log/pm-suspend.log and everything seems normal, meaning I am not seeing any failures.

Any ideas where I should look next?
