bluetooth keeps turning off in 19.04 after physically and manually turning off bluetooth device, any fix to this?

I keep having my bluetooth turned off in ubuntu 19.04. it happens if I physically turn off or disconnect my Bluetooth speaker. Bluetooth in ubuntu 19.04 won’t turn on even if the slider is on “on” mode. I have to restart ubuntu several times to make it work. I already reinstalled Bluetooth but still, it happens.

anybody here who has the same problem or have a fix for it?

thanks 🙂

Ubuntu 19.04 boots to blank screen with dual monitors and AMD Radeon HD 7730

I just loaded Ubuntu 19.04 onto my Dell XPS 8500 desktop last week. I am using an AMD Radeon HD 7730 with dual monitors (1 HDMI, 1 DisplayPort). Most of the time when I reboot my system, it will boot to a completely blank login screen. It shows nothing at all, just a blank screen. I have tried the things below and nothing is working. Deleting the raven_dmcu.bin file seemed to work but now I’m having the problem again. If anyone could please tell me how to fix this, I would very much appreciate it. I don’t want to have to buy a new video card but I’m going to have to if I can’t get this fixed. I have got all other issues on my system worked out except this one. Thanks.

1 – Tried switching monitor 1 and 2 cables and adjusting the display settings to put their left/right orientation back. 2 – I read someones post that said this would work and it did for a while but I’m having the issue again now. Delete the file /lib/firmware/amdgpu/raven_dmcu.bin and then run sudo update-initramfs -u -k all

Slow booting in Ubuntu 19.04 with full disk encryption

I have an 960GB SSD (Kingston A400) installed on my laptop (Asus X505BA). I installed Ubuntu 19.04 with full disk encryption. I also have enabled fastboot and secureboot in the UEFI settings. My problem is that the system decryption at boot is really slow. It usuallly takes 4 to 5 minutes wich is too much compared with the booting time I used to have with a non encrypted HDD in the same laptop (usually 1 minute or less).

What can I do to improve this?

Upgraded 18.04 -> 19.04 – Blinking cursor, KDE 5 not starting

I have been researching and trying to fix this problem for days now, nothing seems to help.

What I did

  • Few days ago I installed KDE Plasma 5 (5.12 or lower, don’t remember exactly)
  • After that I upgraded to Ubuntu 19.04 (and also to KDE Plasma 5.15)
  • When booting to Linux, it shows Kubuntu logo for some time and then gets stuck on blinking cursor ( _ )
  • I used Ctrl + Alt + F2 to go to the tty thing where you can run commands
  • startX started finally after some research but it crashed as soon as the password dialog popped up also, I don’t want Gnome, I want my KDE
  • kstart5 plasmashell should start the KDE Plasma desktop environment but instead I get these errors:
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.   This application failed to start because no Qt platform plugin could be      initialized. Reinstalling the application may fix this problem.  Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.  Aborted (core dumped) 

I uninstalled my AMD drivers because these were meant for Ubuntu 18.04 only but later I found patch to make the Ubuntu 18.04 drivers work on Ubuntu 19.04, but that didn’t change the situation, still KDE won’t start.

I also installed the latest MESA drivers.

Machine recently started freezing. Ubuntu 18.04 and 19.04. Kaby Lake GPU with intel HD 620

* Ubuntu 18.04 & 19.04 keep freezing due to video driver issues *

Until about a month ago, I had been running Ubuntu 18.04 successfully on my Dell Latitude (7th Gen Intel i7 processor, Kaby Lake, and Intel HD 620 GPU).

However, after a recent update to 18.04, I am experiencing constant freezes, after ive been logged in for 2 to 5 minutes.

I tried reinstalling 18.04, and upgrading to 19.04, neither solved the problem.

I know that the issue is related to my video drivers, because if I edit the grub to ‘nomodeset’, the machine will boot and run (but obviously with very poor video performance).

Ive tried installing the ppa open graphics drivers /oibaf drivers, but that doesnt work either. After installing, I check my drivers to ensure that the box for the oibaf drivers is checked (within ‘other software’ in the drivers app), and restart… and inevitably when I restart, the system is still using the i915 drivers.

(I run ‘lshw -c video’ within terminal to see which video driver is being used, and my system seems to still be using the i915 driver, which is causing the crashes)

Is there anything else I need to do to force Ubuntu to use the PPA drivers?

Hoping one of you fine people can help me out here?

Ubuntu 19.04 fails to boot following upgrade from 18.04

I recently upgraded from 18.04 to 19.04 but have been unable to boot into 19.04 since the upgrade. The boot process is failing somewhere after GRUB, I get a nice graphical prompt to unlock my encrypted drive, followed be a terminal screen of [ OK ] and the odd [FAILED] line. These scroll too fast to see what they are, but one is Failed to start NVIDIA Persistance Daemon. I can get to the Recovery Menu and have tried re-installing nvidia drivers and also tried adding nomodeset to the GRUB config. The network DNS is broken when I drop to the root shell from the Recovery Menu but this can be fixed temporarily by modifying the /etc/resolv.conf file. If I try failsafeX I get a window stating that “Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself.” If I try running the default graphical mode, I get sent back to the recovery menu. The other options to configure myself, don’t seem to take effect when I press OK, and just stays on the option window. I am not sure what to do at this stage. The PC is a Dell Precision M6500 laptop with an Nvidia FX2800M (G92GLM) graphics card and was working okay on 18.04 prior to the upgrade.

Ubuntu 19.04 + Nvidia MX150

i can’t find any related info about this, maybe because of how new 19.04 is?

I don’t see the proprietary drivers in the additional software window… I only see the open source drivers which don’t perform very well…

I’ve tried all kinds of things to improve performance here, install the .run file from the nvidia site, use bumblebee (never got it to work either because the nvidia module is not loaded or something like this).

Also if i install the .run file from the website, glxgears shows me thousands of fps, but the games don’t work and ubuntun in general is really laggy…

Any idea what else could i try? OH, i also disbled the secure boot. THanks and regards!
