I had done a sudo apt-get upgrade and was installing some packages(truffle,nodejs) when my laptop stopped responding and applications were not opening so I restarted it and when it booted it got stuck in the verbose boot screen and blinking intermittently.
All were showing [OK] so I pressed ALT + F2 and was able to login but it showed a few python value errors in file “/usr/lib/python3/dist-packages/lsb_release.py”
ValueError: could not convert string to float: '6.06 LTS'
How can I fix this and complete the boot sequence please help?
I recently moved my work computer home and hooked it to new monitors. One monitor works perfectly, the other (an AOC monitor connected via displayport) flickers and tears occasionally, and then will put itself to sleep and I have to disconnect/reconnect it to the computer to wake it up.
I never had this problem previously with other Dell monitors at the office. I had the problem with 18.04 so tried updating to 18.10 and the problem persists. I’ve also tried changing the refresh rate to no avail.
This is the output of

I’m stumped. Any suggestions welcome.
as posted before (19.04 gnome session login – is it impossible without mouse?) this seems to be the case.
apart from that, I’d like to know how to get the top-right settings/shutdown menu just by using the keyboard.
I updated ubuntu 16.04 LTS to ubuntu 18.04 LTS. On ubuntu 16.04 I was using gdm3, which got broken during upgrading because when I set gdm3 as default display manager in recovery mode through,
sudo dpkg-reconfigure gdm3
it said “gdm3 is broken or not properly installed” so I set lightdm as default display manager.
Now, when I boot having lightdm, after the purple scree, the black screen appears and nothing happens. If I press Ctrl+Alt+F2 , it shows me the tty3 login screen. I login with my username and password. Sometimes, it accepts it and sometimes it doesn’t (which is an issue but not the major issue of this question).
After logging in, I can navigate my directories but I can’t open graphical window. I tried opening chromium using command “chromium-browser www.google.com” but it said something like “Graphical interface not permitted”.
How do I get my Graphical Interface back? Note that I can’t connect to wifi. I tried using
sudo ifconfig wlan0 up sudo iwconfig wlan0 essid name key s:password
It gave error in setting password which was like “Invalid argument password, Set encode”. I tried giving hexadecimal password too without s:
sudo iwconfig wlan0 essid name key hexpassword
Didn’t work either. How do I get my UI back? And can the internet be connected through ethernet?

I updated ubuntu 16.04 LTS because on 16.04 every time I start my computer, The folders and files gets locked. I used to solve them with “fsck /dev/sdaX” where X denotes the Partition number i.e. sda1 , sda2 etc and restart my system but it would waste a lot of my time. I tried different ways to solve this issue but couldn’t so I updated my OS with the hope that it would solve this issue.
When the updates were installing, in the middle the login tty1 screen appeared and I logged in and reboot the system because nothing happened after login. But when I rebooted, the system won’t make up to Login Screen. Instead it’s stuck on purple screen with one dot under ubuntu logo.
I tried recovery mode through GRUB, enabled network and selected root, entered root password but then when I run commands like “sudo apt-get remove plymouth”, “sudo apt-get install lightdm” etc. They are not executed and the system suggests me commands but when I use to suggested commands, they aren’t executed too.
(I know that it’s duplicate but my problem is not solved from answers of the previous question like this one so technically it’s not a duplicate. I am a software developer and I can’t lose my data plus I need to get back to my development environment ASAP.)
First at all, take easy I’m a novice in Linux world 😀 I’m using my laptop (L502x) and one HDMI monitor extended. Built-in display is my primary screen and second monitor is extended. I always use HDMI plugged, but not ever my second monitor is turned on. In this case when I start my laptop Ubuntu show me login screen just only on extended monitor forcing me turn it on and logging… After that I can power off second monitor and using my laptop ordinarily. There are some way to force Ubuntu to show login screen in built-in monitor or who know in both at the same? Ubuntu 19.04 Driver Nvidia-390 VGA 525M

I install Ubuntu 18.04 with the amdgpu driver for my rx580 and I’m continuing to get screen tearing occasionally with windows and during video playback. I’ve enabled TearFree, DRI3, and a couple others in my xorg.conf.d file but none seems to have any effect.
here is my current config
Section "Device" Identifier "Card0" Driver "amdgpu" BusID "PCI:1:0:0" Option "DRI3" "3" Option "AccelMethod" "glamor" Option "TearFree" "true" Option "VariableRefresh" "true" EndSection
I’ve fixed this on other linux machines using compton but to my knowledge I’m not able to change the compositor used by gnome. Not sure what the next step is to trouble shoot this issue.
When I’m working with Ubuntu and doing my usual work, suddenly I see a black screen. I can hit ctrl+alt+F1 and GNOME login appears. So I can Login again and come back to the session with all windows opened.
This problem happened to me about 10 times in 2 months. This is my log when the problem happened:
2:35:26 AM gnome-logs: Failed to load module "unity-gtk-module" 2:35:26 AM dbus-daemon: [session uid=1000 pid=2791] Successfully activated service 'org.gnome.Logs' 2:34:46 AM gnome-shell: Window manager warning: Overwriting existing binding of keysym ffe1 with keysym ffe1 (keycode 32). 2:34:44 AM dbus-daemon: [system] Activating via systemd: service name='org.bluez' unit='dbus-org.bluez.service' requested by ':1.216' (uid=1000 pid=22053 comm="/opt/google/chrome/chrome " label="unconfined") 2:34:38 AM gdm-x-session: (II) event3 - Microsoft Microsoft® Wireless Laser Mouse 8000: device is a pointer 2:34:38 AM kernel: rfkill: input handler disabled 2:34:38 AM acpid: 1 client rule loaded 2:34:38 AM gdm-x-session: (II) NVIDIA(0): Setting mode "DFP-0:nvidia-auto-select" 2:34:38 AM gnome-shell: clutter_input_device_get_device_id: assertion 'CLUTTER_IS_INPUT_DEVICE (device)' failed 2:34:38 AM gdm-x-session: (II) event2 - Microsoft Microsoft® Wireless Entertainment Keyboard 7000: device removed 2:34:38 AM gdm-session-wor: gkr-pam: unlocked login keyring 2:34:30 AM gdm-x-session: (II) event1 - Power Button: device is a keyboard 2:34:30 AM acpid: 1 client rule loaded 2:34:30 AM gdm-x-session: (II) NVIDIA(0): Setting mode "DFP-0:nvidia-auto-select" 2:34:27 AM gnome-shell: g_array_unref: assertion 'array' failed 2:34:27 AM gdm-x-session: (II) systemd-logind: got pause for 13:67 2:34:27 AM kernel: rfkill: input handler enabled 2:34:26 AM acpid: client 2785[0:0] has disconnected 2:34:26 AM gdm-x-session: (II) event2 - Microsoft Microsoft® Wireless Entertainment Keyboard 7000: device removed
I’m using Ubuntu 18.04.2, GNOME Shell 3.28.4 and Nvidia 390.116 driver.
I didn’t remove the Keyboard which I see on log. RAM and CPU usage are normal.
What is going wrong?
After I did the upgradation of ubuntu 14.04, after booting, the login screen is not coming. It is just a black screen, but sometimes I can see a mouse pointer with an ‘x’ as the cursor. Also the system is dual boot. But windows is not available in the boot menu. There are three types of kernals in the boot menu. 4.4.0-128, 4.4.0-116, 4.2.0-42. All of them are giving the same error. The pc has a zebronics motherboard.
