14.04 – Ubuntu 20.4 LTS keeps FREEZING

iam a big fan of ubuntu. i came back to ubuntu after i used windows 10 for while. i do a clean install of Ubuntu on a core i7 machine with 500 gb SSD and Nvidia Gforce GTX 1050 Ti. after a successfull installation and update, i do restart and the restart took forever and cannot complete. it shows so many strange message. i force to shut down my laptop by pressing the buttun. i turn it back on, and it goes normal. but once i install and open some apps, the ENTIRE system was FREEZING. only mouse moves. i press the Shut down button again. this thinghs happens multiple times that i cannot count it. and i do reinstall again and again, but the exact same problem happens. few months ago before i switched to windows, this annoying thing is the only reason i swithed back to windows. i have tried so many solution i found on Internet, and none of them work. My Laptop was runnig perfectly on windows. but not in Ubuntu. i saw many people got this issue and they find no solution. can anyone please tell me what Happen with Ubuntu?

14.04 – Quick folder acces on ubuntu – Go to the folder and not make a search

So there’s something that’s bugging me on unbuntu, never figured out how to fix it.

On windows 10, if I have multiple files in a folder and I type the first letters, it select automatically the folder starting with the same few letters.

On ubuntu, it instead does this:
enter image description here

Ask you can see, it does a search of “goo” instead of highlighting google-chrome directly.

Is there any way to fix this?

Thank you!

How to upgrade from Ubuntu 14.04 (32-bit) to latest Ubuntu Budgie (64-bit)?

Ubuntu 14.04 (32-bit) is installed on my laptop along with Windows 7. I have barely used Ubuntu, but I’m on it now since Windows is troubling me.

I was looking for a Ubuntu flavour that is light-weight, and I found Ubuntu Budgie, which is also pretty sweet looking, hence I opted it.

I’d be highly grateful to you, shall you could give me exact steps on how I can update to the latest version of Ubuntu Budgie (64-bit version.)

Please let me know if I need to update Ubuntu 14.04 as well.

Note:

-When I was trying to update the OS using Software Updater, I would get the error, “Requires installing from untrusted sources.” And I’d have two options, “Settings…” (which leads to the Software Updater) and “Close”.

Related Queries:

-Does all the flavours of Ubuntu require the ‘original’ Ubuntu to be installed, or they are stand-alone operating systems?

-I need an operating system which is ligh-weight and can run most Windows softwares. Is Ubuntu Budgie a good pick or should I go for something else?

Memory: 3.9 GiB

Processor: Intel Core i3-2350M @ 2.30GHz x 4

14.04 – How can I get Ubuntu 14 to recognize my second monitor?

My workstation has dual DisplayPort. Dual monitors work as expected on Windows 10. Switching to Ubuntu 14.04, only the primary DisplayPort (always the “top” one on the IO shield, never the bottom) is initialized. I can tell because the bad port causes a “No signal” message to whichever monitor is plugged into it, regardless of the monitor or cable. So the “detect” option in Ubuntu’s Display settings is useless. This seems like a blatant driver issue, but I’d like input on the best course of action for getting dual monitors to work. Here’s lspci:

$ sudo lspci -v

Here’s the value for Graphics in “Details” (Gallium 0.4 on llvmpipe (LLVM 3.8, 256 bits))

On Windows, the Intel HD 630 Graphics driver for my Coffee Lake Intel CPU works like a charm. BIOS Video option is set on “Auto” (as opposed to Intel), which makes no difference.

Do I really have to install Intel Graphics Stack Recipe from scratch? This seems like the least user-friendly option, and I’m not even sure that it would resolve my problem.

I’ve tried the Intel Linux Graphics Installer, but this has been discontinued as it is no longer on the https://01.org/linuxgraphics/downloads page.

I have yet to try GRUB options. Willing to attempt anything that might work… except downgrading display manager to gdm from lightdm, as I’ve tried this and it sort of ruined my OS.

linux – Ubuntu 14.04 poor performance in some operations

Few days ago something just happened, even not sure what. But some operations very slow. Server is virtual.

Disk, Memory, CPU all normal with minimum load. fsck shows no errors.
top, htop, iotop, stress --cpu 8 --io 4 --vm 4 --vm-bytes 2048M --timeout 10s all ok.

I even have no idea what to check else.

For example service slapd start couple days ago taken 2 sec. Now it takes 31 sec.

smbd even can’t be started, timeout I suppose.

SSH login takes 30secs in each step. Password, sudo etc.

What can be checked else?

Logs are clear, like nothing happens

14.04 – Gtk-WARNING **: cannot open display: IP:0.0

I’m using ubuntu desktop 14 and doing local request (not remote). I’m not using putty to connect to the server from Windows but I’m using my own ubuntu and do gksu (ex: gksu nautilus) on that ubuntu to display an app on that ubuntu. Whenever I’m trying to use use gksu, it shows this error:

Gtk-WARNING **: cannot open display: IP:0.0

I have tried many tutorials and I have done these things below but it still give me that error:

  1. Type Export DISPLAY='IP:0.0'
  2. Type xhost + (it give me an error xhost: unable to open display "IP:0.0")
  3. Add Defaults env_keep="XAUTHORIZATION XAUTHORITY TZ PS2 PS1 PATH LS_COLORS KRB5CCNAME HOSTNAME HOME DISPLAY COLORS" to /etc/sudoers
  4. Set X11Forwarding yes and X11DisplayOffset 10 in /etc/ssh/sshd_config and ForwardX11 yes in /etc/ssh/ssh_config

I upgraded from 14.04 to 16.04 (do-release-upgrade) with mysql version held. When trying to upgrade to 18.04, please install updates

I was able to upgrade using do-release-upgrade from 14.04 to 16.04, while holding mysql version. When I try to upgrade to 18.04 I get error to install updates for release before upgrading.
Is it possible to upgrade with mysql still on hold?
