Laptop sometimes shows underscore in corner, becomes unresponsive when opened

I have a Dell XPS 15 with a GTX 1050 GPU running Ubuntu Budgie 19.04, and I have the 418 drivers. Recently, my laptop has been occasionally having a problem where when I open the laptop, instead of showing my lock screen, it shows a black screen with a small underscore in the upper left corner. Sometimes I can press ctrl-alt-f1 to see a login prompt, but I can’t type anything or switch to any other console. The only way to use my computer again is to hold down the power button until the power is cut and turn it back on again. What is causing this, and how do I fix this?

Ubuntu Server 18.10 Web Server – Unresponsive daily

I’m running a Ubuntu Server 18.10 (GNU/Linux 4.18.0-1015-gcp x86_64) on Google Cloud. It’s using 4 cores and 14 GB of memory.

Every night at approximately 05:00 UTC (sometimes a few minutes before, sometimes a few minutes after) the whole server becomes unresponsive to any traffic. Web requests fail, can’t ssh or ping the machine. It remains in this state for 2-5 minutes then comes back. This occurs during the middle of the night for most users, so does not seem to be load related.

Afterward, in the performance history graphs, I can see that during that time the CPU usage dropped to less than 1% usage.

The machine does not seem to be running out of memory, leading up to the crash usage was low, and rarely exceeds 10 GB.

The syslog doesn’t show anything obvious, at least to me. I’ll post a screenshot of what went on during that time below.

There are automated tasks/crons that run at various times of the day (database backups, disk cleanups, etc) but none seem to line up with when the server becomes unresponsive.

If anyone has any suggestions as to what could be happening or ways to gather more info it would be greatly appreciated.


Desktop unresponsive after Disco Dingo Upgrade

I am experiencing some weird and very annoying UI issues after the Disco Dingo upgrade.

I have a NVIDIA Graphics Card.

My issues include no feedback from mouse clicks in the desktop environment and no feedback from keyboard events in the desktop environment. I have tried reinstalling the nvidia graphics drivers, changing the display manager, “disabling” wayland with gdm3, and reinstalling the gnome shell (fix GUI after Disco Dingo upgrade).

I dont know what else to try – PLEASE HELP!

After Factory Reset, Android Galaxy Camera Touchscreen is unresponsive

I met the weirdest thing I ever have. I have a galaxy camera gc100, It works very well without any problems. Since I decide to lend it to my friend, I did a factory reset. After the factory reset, everything looks fine and the initial setup screen “Select language” appears. BUT, I can not touch anything on the screen. It seems that the touch is simply unresponsive at all until the screen turns off by timeout. And then I tried (1) hard reboot, (2) go to Maintenance boot mode by pressing power and zoom out and did delete cache and factory reset again. (3) flash stock rom. (4) take out of the battery and then holding pressing the power button for more than 1 minute and then insert the battery and boot. (did three times). But none of them works. This is just weird and I can not find anyone on the Internet having the same issue as me. Other people met unresponsive touch screen and then did hard reset to fix the issue. Mine is entirely opposite. I don’t have any problems, but factory/hard reset causing the touch screen is unresponsive at initial setup screen. Do anyone have any clue how I can workaround this issue? Thanks a lot. (Btw the system is still functioning because I can adjust volume and take screenshots by using the physical buttons).

Seagate Backup Plus 5 TB became unresponsive after long period of use

I recently purchased a new Seagate Backup Plus 5TB for data use, because none of my drives are functioning properly. My old Seagate Expansion 2TB hard drive failed (“Unable to repair”); the Seagate Backup Plus 5TB that I borrowed became unresponsive after a period of use and has bad block (while writing it auto-rejects the drive); and the Seagate Backup Plus Desktop 5TB became unresponsive after a period of use.

After using the new drive for a while, I discovered that it will hang after 2-8 hours of continuous writing. By continuous, I mean literally all the time (downloading youtube videos and multiple torrents). I have read that hanging suggests bad block, and bad block suggests broken drive. What should I do? I’ve also heard that Seagate is not very reliable as to the quality of hard drives. Is it true?

My keyboard becomes unresponsive when i play audio

So i just installed Ubuntu and i’m noticing that whenever audio is playing through my headphones the keyboard just stops doing anything. The lights on it are still on it just doesn’t type for a few minutes. I’ve figured out that if the audio is playing through my monitor’s built in speaker nothing happens, only my headphones, and i’ve updated my keyboard drivers several times.
