Samuel Osoba's questions

I installed Ubuntu 22 on HP Elitebook 6930p Core2Duo laptop.

See my BIOS Configuration below:

• Sata Device Mode = AHCI
• USB Legacy Support = Enabled
• Virtualization Tech = Disabled
• TXT Technology = Disabled
• UEFI Boot Mode = Disabled

After installation using the Erase Disk & automatic partition option through the USB installer, the installation was succesful, I restarted the PC and I was asked to remove the installation disk and press Enter.

After following the Remove Installation Disk & Press Enter instruction

I did not enable UEFI mode because I read that is better to install in non-UEFI mode if the PC is pre-2010 from here - https://help.ubuntu.com/community/UEFI

System restarted and says Non-system disk or disk error

What I have Done

• I booted with LiveCD (USB-installed)
• Opened GParted, switched to the Sata Disk to view the partition structure, and here is what I found:
• /dev/sda1 -- Name: unnamed (File System: grub2core.img - 1.00mb)
• /dev/sda2 -- Name: EFI System Partition (File System: fat32 - 513.00mb)
• /dev/sda3 -- Name: unnamed (File System: ext4 - 185.81GB)

**NB: The EFI parition /dev/sda2 line had a red color exclamation mark, when I clicked on it, an error message was displayed.

Error Message on EFI Partition: Unable to read the contents of this file system! Because of this, some operations may be unavailable. The cause might be a missing software package. The following list of software packages is require for fat32 file system support: dosfstools, mtools.**

To know if my system booted in UEFI or Legacy mode I had to run this command below in terminal to check:

[ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD"

The command the result below, the result showed that my installation and boot into liveUSD after the boot issue is in legacy mode:

Legacy Boot on HDD

Any ideas for proceed from here?

Thanks in anticipation.

Having installed Ubuntu since last year, everything worked on my PC like it did on my removed Windows 10 OS except the inbuilt mic:

Below is my device configuration:

~$ sudo lspci -knn | grep Audio -A3

I also queried my audio devices using this command cat /proc/asound/card*/codec* | grep Codec below is my result:

cat /proc/asound/card*/codec* | grep Codec
Codec: IDT 92HD90BXX
Codec: Nvidia GPU 14 HDMI/DP
Codec: Nvidia GPU 14 HDMI/DP
Codec: Nvidia GPU 14 HDMI/DP
Codec: Nvidia GPU 14 HDMI/DP

I also downloaded vokoscreen to check pulse and alsa-server options and also test, the tests produced failed results without audio tone captured at all except noise.

See screenshots of my test options below:

The final step I tool after testing with VokoScreen with failure was to download QasMixer, upon opening QasMixer, I have the screenshot below:

Initially, when I open QasMixer, the Mic line with 12:00db was not selected at all, so I selected it, meaning I enabled, all this efforts only resulted in the MIC icon showing at the top right of my screen next the speaker icon with volume indicator but mic is still not working.

What else could I be doing wrong.?

I searched the entire web for help about how to upgrade wine from 5.0 to 6.0

My current version of wine is queried from terminal, see below:

 Wine is a free MS-Windows API implementation.
 This is still a work in progress and many applications may still not work.

 This package provides essential wrappers and convenience tools for the
 standard Wine components. It also employs the Debian alternatives system to

Thanks for your input.

After installing Davinci Resolve 17 last week on my Dell Precision 4600 Nvidia 1000M 2GB Graphics, I observed that the software was not detecting my GPU hardware; after some hacks, I was able to bypass that.

Now, a new issue came up, after editing a video, when I click on the Deliver tab; the app freezes immediately. After multiple efforts to resolve that, nothing worked, it continues to hang when I click on the Deliver tab.

Now I picked KDenLive and that seemed to work great.

My issue is now is:: How do I uninstall DaVinci Resolve, I actually installed it using the .run file and building a .deb install using MakeResolveDeb.

Below is is the command-line devices I have;

(base) s***@syncserve:~$ cat /proc/asound/card0/codec#* | grep Codec
Codec: IDT 92HD90BXX

(base) s***@syncserve:~$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)
01:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev ff)

The problem is the microphone does not work on, though on all the management interfaces, there is always a default microphone showing, and in the top-left bar for sound, the mic signal indicator is available but does not respond to sound input test.

One thing I know is that I have never installed the audio drivers for the above hardware devices since I set up the laptop; how do I install the drivers for the mic?

Ubuntu 20.04

I switched to Linux completely 4months ago. I have been able to install Anaconda in my Ubuntu 20.04, but I observed something which is like a headache.

After setting up an environment, I needed to change the Python version it uses from 3.10 to 3.8. So I used these commands:

conda activate my_env  
conda install python=3.8

which is the standard way of doing it in Anaconda.

However, I observed that it downloaded new Python 3.8 packages into the environment, despite the fact that I had Python 3.8 already pre-installed on my system.

How do I configure my conda environment to use the existing Python version already installed on my system without downloading a copy from the internet?

Here is what happened; I tried to upgrade python3.8 to 3.9; my goal was to Install python3.9 and then force my system to start using 3.9 instead of the current 3.8.

Then I found thsHow to Upgrade to Python3.9

Ignorantly without reading the comments, I jumped into my terminal and started executing the install and update-alternatives commands; at the end of the article; I discovered that I wrote a small python program and discovered that I could not run it.

That was when I decided to go through the comments, and discovered that some dependencies were missing; having tried to install dist-utils for 3.9; my system did not allow any install, kept saying it's available or something so I ignored and decided to quickly go back to my 3.8 having read some articles here warning against messing with default python installations.

Initially, my fear was that I have broken the default python installation; even though I never attempted removing it, so I decided to switch back to the old 3.8 I had working well.

I did was simply following the same article which gave room for switching between the python versions and switched back to 3.8; now it appears I'm fine.

My question is how to setup the installed 3.9 so that I can have it function properly?

Having tried many standard terminal commands for removing Telegram which came up Ubuntu 20.04 after installation. All the commands returned error: there is no app like that on the system, though I keep seeing the app on the list of general applications and I can also open it, but not login into it. I tried the following commands:

samuelson@syncserve:~$ flatpak uninstall org.telegram.desktop/x86_64/stable
Command 'flatpak' not found, but can be installed with:

So, I figured that I needed to check via command for all the paths directory exists if any; hence I used the command below to check all possible paths for telegram:

find / -iname "*telegram*" 2>/dev/null

The output of the command was surprising, it was such a long list of directories for telegram, see below.

My issue here is how do I remove this program?

samuelson@syncserve:~$ find / -iname "*telegram*" 2>/dev/null
