I tried to upgrade from 18.04 to 20.04 and got the same error. The problem was that the 'bionic-updates' channel wasn't active in my /etc/sources.list I had only 'bionic' and 'bionic-security'. After adding a line to the sources.list: deb http://hu.archive.ubuntu.com/ubuntu/ bionic-updates main restricted sudo apt update && sudo apt dist-upgrade it ...

I have the same problem with gnome sometimes when I do something. Try to switch to text mode and back to graphical mode (CTRL+ALT+F3 and then CTRL+ALT+F2). Sometimes gnome just hangs for me, espacially when I use VirtualBox or Copy Paste stuff.

No one faced this issue it seems?.. It has definitely something to do with graphics card bug coping up with refresh rate. Or perhaps heating hardware as sometimes it works for day without this issue. Sometimes frequently blanking out and refresh rate drops too..

I can confirm this behavior. This might be a duplicate, but it was the first relevant article I found, please do not delete it. After looking at the other post, I do prefer this one. Every day after starting up the Dell XPS 15" laptop on Ubuntu 20.10, I have to toggle the natural scrolling OFF en then ON to get the mouse scrolling to perform as expected....

Yes you can. The magic word is Wineprefixes, see here: https://wiki.winehq.org/FAQ#Wineprefixes There's also a GUI solution called playonlinux (name is misleading, it's not only for games). You can use it to manage wineprefixes, wine versions, create launchers etc.

Thanks but problem is when you are typing bangla, suddenly in the middle, the application stops working. Nothing seems to fix it the problem. Only, when the User have to log out + in to activate the application again! Need help on this.

I just encountered this issue after upgrading a VM from 20.04 to 20.10. I tried the solution proposed by Loadn Abox apt install --reinstall resolvconf network-manager libnss-resolve Unfortunately this did not work for me. The only solution was to edit /etc/systemd/resolved.conf and add entry: [Resolve] DNS=192.168.2.1

Restarting gdm3 worked for me in ubuntu cli! First check your gdm3 status by typing sudo systemctl status gdm3 After entering see whether all parameters are proper and are running or not. In my case some parameter failed to run. So I restarted gdm3 by entering the command sudo systemctl restart gdm3 This worked for me. Hope it helps others.

Brasero should have came with your distribution. You can also try to install one from the Software Store. If you are more of a power user you can: sudo apt install synaptic sudo synaptic Then search for a number of the burner software options. I personally use k3b for my DVD recordings.

Heyy by choosing more options, there should be an option "free space" that's where you put your Ubuntu. But in your case it's not there, the partition that you created must be a unallocated partition (The color should be black in disk manager) for you to install Ubuntu.

You should be able to access a terminal with Ctrl + Alt + F3. Then log in with your username and password. TTY I think it's called. It is full screen so, I would recommend to install a terminal immediately so you don't have to stay there for everything. sudo apt install gnome-terminal Ctrl + Alt + F2 should put you back in unity. If not, try the other F#'s ...

Andrew's comment regarding the different installers was the right thing. I just made the (obviously bad) assumption that the kernel/initrd bits for the ISO installer would be the same as the network installer. I switched to the bits from the ISO and now it all makes sense.

Never mind — I stumbled on the cause of the problem, and it was VMware. 🤦‍♂️ When I went into the VM settings to delete the virtual disk, I found that unbeknownst to me VMware had inserted another virtual CD drive using an image named “autoinst.iso”, as well as a virtual floppy using the image “autoinst.flp”. I had explicitly created the machine without a ...

Looks like you've added some "Other Software" to your apt list. A clean one looks like this: If you've added more remove them one by one... If that ppa is not on the list, you might change the server on the "Ubuntu Software" Tab, left of the one on the picture...

Nomodeset is for testing and should not be used all the time. Since you are using a NVIDIA card I suggest you are installing the NVIDIA drivers from the "Software & Update" app in Ubuntu. Just search for "Additional drivers" in your "Activities" and it will install the appropriate drivers. Remove the "nomodeset" ...

Answering my own question. Turns out one can use emacs26 or emacs27, although my own experience is with emacs26. Here's what I ended up doing: sudo apt-get install emacs which installed emacs 26.3 build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.14 As for the JDEE environment, I followed the doc provided here, which is to use MELPA and emacs own package ...

I have the exact same problem. A temporary fix is to logout, change the environment from Unity to Gnome or something else and login. Gnome has a dropdown application menu that lists everything. I haven't found the solution for Unity yet.

Sorry for interupting, This may not be an ideal go around, but maybe a temporary solution. I also face the same problem, in my Ubuntu 20.04, and I decided to install the flathub version instead and its being running fine up till now. https://flathub.org/apps/details/com.calibre_ebook.calibre

The problem happen only when you want to copy your system+home data to the new media. In that case even if you have the correct permissions to allow the copy in all your dirs and files you will get the system copy aborted with Errno: 22. The issue can be bypassed with unmarking the option: Copy user data files In this way it is possible to copy ...

Not for suspend, but for hibernate Linux uses the swap. You need to have a swap space activated bigger than the actual RAM memory in use. Suspend keeps the information in memory at the cost of a small part of battery, I've observed 0.5% to 1% of battery per hour suspended. Hibernate swaps the memory to the swap space and completely powers off the computer, ...

You should just need to install the desktop packages you want. Packages like ubuntu-desktop will provide a lot. See also: Switching from Server to Desktop Installed 16.04 server on my laptop.

OP here. Found the problem. I didn't realize that the flash drive with the Ubuntu ISO had to be partitioned/formatted GPT/UEFI. Once I fired up my Windows VM and installed Rufus and used that to make the install flashdrive, I was able to install Ubuntu on the second laptop. Thanks!

I get this issue on systems that use the onboard graphics. Typically an application, often Chrome when moving the window, will get stuck and the window manager stops responding. When this happens, CTRL-ALT-F1 and run top, and the window manager and the application will both be pegging the CPU. Often I can just kill the application that is causing this ...

As on your screenshot, you have three ethernets: eth0, eth1, eth2 . eth0 has an IP, so you have some config for this (ie by ifupdown with /etc/network/interfaces config). I hope eth1, eth2 is not connected to the same switch and network, to get this works it needs more settings. You should check, that any other tools like ifupdown not used for bringing up ...

Either you go into a different tty at boot (Ctrl+Alt+F2) or you do it from recovery mode and dropping into the root prompt. Either way, all you have to do is type: rm .config/monitors.xml To get rid of the fractional scaling config

I have similar problem as yours on my Thinkpad W520 and similar CPU error message. It is a hardware issue as I tried switch to Windows 7 and my screen flickers the same way. I think it is related to overheating since after I increase fan speed to maximum using "thinkfan" I rarely have the problem anymore.
