The weirdest thing is happening.

If I download .mkv files in Ubuntu, save them to my external drive and then try to play them on Samsung TV - the TV says that file format is unsupported. But if I download the exact same file in Windows 10, then there are no issues and video plays just fine on my TV.

The external drive is formatted in NTFS format and i use qBitorrent for downlaoding mentioned .mkv files. Ubuntus version is 19.10

Why could this be happening?

I am attaching external drive to the TV directly.

I own a Lenovo Yoga 710 laptop with Intel Core i5-7200U processor integrated Intel HD Graphics 620 (Kaby Lake GT2).

The graphical performance in Ubuntu 18.04 running kernel 4.15.0-33 seems to be a bit choppy. The animations are not that smooth. Compared to Windows 10, it's quite a lot worse.

I have been reading about it and have found such terms as Vulkan and Mesa, but they seem to be outdated and Intel itself doesn't provide official drivers for Linux.

My question is: are there any ways to optimize and improve graphical performance for Intel graphics?

I have followed endless amount of guides in order to make primus work with steam in ubuntu 14.04 and yet nothing works. I would like to completely purge everything that is associated with nvidia, bumblebee, nvidia x server, primus, prime indicator and so on. Can I do so?

Does software exist for ubuntu 14.04, which would notify you about facebook notifications, notify you about new emails and so on? If so, I would like to ask you to mention it. Thanks.

f.lux is software which adjusts temperature of your display according to time of the day. Is it possible to make f.lux work in Ubuntu 14.04? If so, maybe you can share your knowledge or point me to a guide.

Previously, I have used ubuntu for a short while. And I have installed 14.04 back then and everything worked perfectly. I was able to connect to all wifi hotspots, to my router as well.

Today, after removing linux distro a couple of weeks ago, I installed ubuntu 14.04 back again and now I have this weird issue:

I am unable to connect to my routers wifi, even though nothing changed in it. All the settings are the same. I have tried to disable routers wifi security - didn't help. I have tried to set up android hotspot and was able to connect to it without any issues. Where should I even start to dig in order to fix this problem?

My wifi card is Intel Wifi Link 1000bgn.

Settings of my wifi network (2.4GHz): Network mode: mixed; Channel width: auto; Channel: 6; SSID broacast: enabled

I have installed Ubuntu 14.04 LTS 64bit, and would like to make sure that TRIM is enabled (as much as I know - it is enabled by default). Is there some sort of command which would help me to find out if it is working correctly?

I am looking for decent equalizer for ubuntu 12.04. Recently, with 13.04 and 13.10 I have tried pulseaudio eq and other eq's. All of them were rubbish. Mainly because the output volume, because of them, decreased about 70% and equalizer it self (other than decreasing volume output) did nothing. I have built in realtek audio chipset. I have not messed around with any sort of drivers, I have completely clean install of ubuntu. Any ideas?
