I've been using Ubuntu in VMs for the past 3 years and finally decided to give the 64-bit version a try on a physical install, however I've been running into few issues:
1. My audio is missing the center channel of my 5.1 speakers, and therefore most of my HD movies have no dialog, and the subwoofer doesn't work either. The default 5.1 sound setting is a total joke and doesn't even work properly. The system software doesn't even have additional audio tuning options for speaker-specific configuration like on Windows. On Windows the driver software automatically adjusted all sound channels as they should be but can't find anything on Ubuntu - the options are simply not there, the settings are barely even comparable to Windows.
2.I've typed my password about a thousand times already to install software, which makes me wish that things should be simple as in Windows (Can't there be some UAC-alike thing in Ubuntu). How can I once for all avoid typing my password each time I want to install something?
Where can I obtain a decent driver for my sound card (SoundMAX ADI 1988B)?
3. I've no resolution to the mouse scroll speed issue, there simply isn't any option in settings to adjust the mouse scroll speed, what kind of modern OS doesn't have this? How can I have this settings without installing any additional software? Add to this a ridiculous default mouse scrolling speed with no option to change it in the OS, and you're left with a rather unpleasant experience.
4. Why can't there be a simple user friendly GUI for Linux software installers? why do I have to mess up with tar.gz files? Why not simply some .exe-alike installers? (.deb is not even close) - Why does this have to be so complicated?
5. I figured I'd update my nVidia drivers. Now every time I've used Linux, I've been scared of this step, as it more often than not, fails. Using the Ubuntu Software Centre, I selected the "tested" nvidia current drivers, and then restarted X to load the new drivers. This as always was a disaster. Upon logging in to the desktop, I no longer had Unity, I recall this happening in 12.04 also, but hoped it'd be fixed by now. Needless to say fixing this involved loading a terminal, removing the drivers, downloading the kernel source and the headers and trying again. This did work, but what a massive pain in the *** which shows that no matter how pretty they make the OS, it's just a clusterbomb of not quite right. I found out that it was some kinda of unfixed bug in Ubuntu itself.
Why do such things have to be so complicated? On Windows you just have to click on a setup file, sit tight and everything is done perfectly without even having to mess up with terminal windows etc.. Needless to say the Nvidia driver feels half baked, not even comparably to first grade Nvidia quality drivers for Windows.
6. How can I move the Unity Launcher to the bottom - they say Ubuntu is so customizable but I didn't find anything about that, nothing except a thread from the 11.xx days with steps that don't even work with 12.10.
7. The default fonts are horrible for the most part, especially distorted and washed out in Chrome. Has something to do with rendering but it occurs even with the default display driver. I have no clue why. I'm using a GTX460 if that matters.
I'm so disappointed in this release as I was expecting a perfect out of the box experience but as of yet, it's still just too much hassle, especially when you have to use the terminal to do almost everything. I almost never used CMD on Windows for basic stuff like installing drivers, configuring the system or doing any complex things. The issue with Ubuntu is with the ease of use and proper software, it's too complex for the average user.
