b-ak's questions

I have a two fold issue since many years. I hope to find a fix now. I'm on Ubuntu Budgie 18.04 and yet again the volume levels are very low.

1. Allow louder than 100% option is gone from the sound settings in Ubuntu Budgie 18.04. So I worked around it using pactl set-sink-volume 0 150%
2. Whenever I hit the volume up/down key, the volume resets to 100%. Then I will have to do pactl set-sink-volume 0 150% again to get louder volume from the speakers.

How do I make, say 150% permanent and map the volume keys to work from0-150%

I have two USB headset and I'm trying to do a two way(Full duplex) communication between them.

$ aplay -l card 1: headset [Sennheiser USB headset], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: C320M [Plantronics C320-M], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0

According to the jackd man page, this jackd -d alsa -P hw:1,0 -C hw:2,0 should do the job.

Jackd shows two capture devices, however the communication is only one way (from Card-2's Mic to Card-1's headphones).

Where am I going wrong ?

A serious issue cropped up just now, I removed my 32bit 12.04 and installed 12.10 64bit version. I followed Creating an EFI partition given at UEFI

Now my system wont boot without my bootable USB stick connected.. It automatically goes into Press F12 to enter boot menu mode without the USB stick

With the usb connected I get this boot screen, with one extra option saying Install Ubuntu OEM (for manufacturers only) Again same UEFI link as above

Ubuntu is installed fine as I can see the 3 partitions I created while Installing UEFI boot partition, / and /home and also this confirms that I have ubuntu 12.10 and Windows 7

And the following image shows the partitions I have, I have made a mistake by creating 2 swaps, I'll rectify it later

Here's my fstab entries

/etc/fstab

The output from bootrepair:

What's going wrong where ?? Please help me..

FYI: I also tried to install 64bit 12.04 when it released, but had problems of windows not being listed in Grub bootloader.

How are partitions in my hard disk handled in Ubuntu? I want to draw parallels with what Windows does.

Let's say I have a HDD formatted as ext4, if I create 2 partitions and mount them at /data-part and /movies, have I created 2 partitions like D:/ and E:/?

I have ubuntu 12.04 running on my system. I repartitioned my hard disk yesterday, I have an empty 40GiB partiton.

Can I mount it at say /data-part ? How do I do this ?

I have formatted it as ext4.

I've decided to make a complete switch to Ubuntu..

My thing is, In windows if the OS crashes (which happens very often) all the data in drives D:\, E:\ etc., will be safe. I format the C:\get the new OS there again.

How do I achieve the same functionality in ubuntu.

Please shed some light :)

I have an alias defined to compile an opencv program which goes like this

alias gcv='g++ -I/usr/local/include/opencv -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_objdetect'

Then I go on to type

gcv imageshow.cpp

I get this long list of errors

But when I use the same command specified in the alias with the .cpp(source code) file in between the Include and Library files (following the suggestion here), everything works like a charm.

g++ -I/usr/local/include/opencv imageshow.cpp -lopencv_core -lopencv_imgproc -lopencv_highgui

Now typing the long command, which gets even bigger as complexity increases, every time is getting difficult, please help me in getting the alias to work or suggest any other alternative.

The brightness of my laptop is reset to max on every restart. I tried the solution provided at this website but had no luck.

This command

cat /sys/class/backlight/acpi_video0/max_brightness

Returns

cat: /sys/class/backlight/acpi_video0/max_brightness: No such file or directory

Then I found that I don't have a folder named acpi_video0, but a folder called intel_backlight:

Every time I increase or decrease the brightness using the brightness control keys, the values in brightness and actual_brightness get updated.

Is there any method I could follow to set the brightness to a fixed value on every boot and vary it as and when I need it using the brightness control keys?

I have lost "Write" permission for myself, and all other permissions for 'Others' and 'Group' on my important NTFS Partition(Contains all my Data). Any amount of Chmod(ing) or using the GUI to set it right isn't working.

I get this error when doing it the GUI way.(No other details of why it couldn't set permissions is mentioned).

And this happens when doing it in CLI. This is quite an issue need help fast.

Output of cat /etc/fstab

Output of dmesg | tail

I would like to remove the VLC nightly build and go back to the default VLC player. I tried sudo apt-get remove vlc which removed it, then I deleted the Nightly PPA and tried to install VLC sudo apt-get install vlc but couldn't as I got a few errors.

There must a proper method, please let me know.

There is a way to show the "Desktop", "All Active Windows" and "Workspace Switcher" by just hovering ur mouse to the edges of the screen.

One way this can be done is using "Ubuntu Tweak".

Is there an application that allows me to extract the audio from a MP4 or FLV video file and store it as an MP3 file for use in a portable media player?

This feature was a really nice thing and its really difficult to get to know the free space available in a partition. Can't we get a tool-tip or something of that sort to display the free space.

Is there a way to get this feature back in ubuntu 11.10.

I really miss the refresh button in nautilus, which has been removed in Ubuntu 11.10. I found it very useful. Is there a way to get it back. :D

I've seen that the Gnome Tweak Tool is not having any effect on the desktop fonts. And the only way to do it is

gsettings set org.gnome.nautilus.desktop font 'Ubuntu 10'

which I read here How to change desktop font and font size

Why is this happening? Is it a bug ?

I'm desperate to buy some of those great things up for sale on the Canonical Store. Is there anything that is being done to bring the store to India or have some kind of a retailer to sell the merchandise here.

At the moment the shipping costs to India is really very high and additionally we may also have to pay up customs for the product purchased.
