I've been reading a book on Gimp. The book recommended that I visit the LinuxWacom Project for the drivers of a Wacom tablet I own.

After extracting the tarball, I have to configure and make install. But this part is where ./configure got interesting.

configure: error: Package requirements (xorg-server >= 1.7.0 xproto xext kbproto inputproto randrproto) were not met:

No package 'xorg-server' found
No package 'xproto' found
No package 'xext' found
No package 'kbproto' found
No package 'inputproto' found
No package 'randrproto' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XORG_CFLAGS
and XORG_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Not to mention my laptop on 12.10 has Xorg version 1.13.0. Not right.

I thought it was as simple as installing the missing dependencies via apt-get, but they didn't work.

john@kotux:~/xf86-input-wacom-0.20.0$ sudo apt-get install xorg-server xproto xext 
kbproto inputproto randrproto

E: Unable to locate package xorg-server
E: Unable to locate package xproto
E: Unable to locate package xext
E: Unable to locate package kbproto
E: Unable to locate package inputproto
E: Unable to locate package randrproto

How can I install these missing packages? I wish the process does not require much manual installation.

I've been having trouble lately with installing the daily build from geary. First of all, I did the following on my terminal, which would get me the latest daily build. Code:

sudo apt-add-repository ppa:valateam/ppa 
sudo apt-add-repository ppa:yorba/daily-build
sudo apt-get update && sudo apt-get geary

Recently, Yorba has released Geary 0.3. But when I installed Geary, the About window shows me 0.2.2+ trunk when it should show 0.3. Perhaps, there is an issue with the package management. I ran this on Ubuntu 13.04 daily build, which updates fine.

I thought by uninstalling geary and installing from scratch would fix the problem, but it doesn't seem that straightforward.

sudo apt-get purge geary && apt-get autoremove

The code removes the app, but doesn't remove any configuration whatsoever. For instance, on a fresh install, my 4 email accounts that I set up were still there.

I really wish to run the daily build on my computer, and I don't want to be stuck with what really isn't 0.2.2+ trunk. How can I troubleshoot this issue and install the daily build? One solution I have is to reinstall the Ubuntu daily build, but I think it's unnecessary.

I always thought that it was MOTU's job not only to bring packages into the universe repository but also make them available in the Ubuntu Software Center. There are many stable releases of applications out there, but many of them are not in the Center.

Is it part of MOTU's job to bring that "some" packages into Ubuntu Software Center?

Although I set the default printer settings through the "printing" manager to NoTumbleDuplex, the LibreOffice print dialog properties isn't defaulted as NoTumbleDuplex. How can I set the NoTumbleDuplex setting as default on libreoffice?

I recently found out about the appAPTonCD and became hugely excited! It could take the packages of my choice in my precise desktop and pack them all in one cd, like my "essentials" installation media. I installed this app and placed my favorite packages into a cd.

Next, I wanted to insert the cd on my laptop running Ubuntu quantal daily build. I navigated to the APTonCd page on the software center, and to my dismay, I realized that it was incompatible with quantal.

Why can some apps, like this one, be incompatible in quantal? Thanks.

I installed a daily build 12.10 on my Mac to test livecd. I already had a pen drive formatted to ext3 labeled casper-rw.

I had to invoke the "other options" with the F6 button so that I could append "persistent", but it didn't work. I clicked "try ubuntu," started browsing the web, and did a restart. When I ran the liveCD again, the persistence failed.

How can I restart in liveCD persistence? Thanks.

I currently help QA team in ISO testing, but I stumbled on a test-case that required some extra research. I just learned about persistence from this wiki page.

Ctrl+F to "Using a loop-back file." Since I will be ISO testing on a Mac, I don't know if it's appropriate to make the file in the root of the partition of my Ubuntu computer.

If the loop-back file is indeed necessary, how can I use it for my Mac computer? If it is as simple as copy-paste, I'll be surprised.

Thanks.

I want to write reviews for applications using another account. In Ubuntu One, it's possible to sign out at will, but I can't do that on the Ubuntu Software Center. How can I change accounts?

I'm still learning about Linux.

As a Linux distro, Ubuntu is blessed with the ability to multi-task, the concurrent execution of programs. And these programs have processes, taking up their chunk of the system resources as necessary.

Process scheduling allows the execution of processes by priorities, so that the higher valued priorities execute more often that the lower valued priorities. But it is a surprise to me that the very important processes actually exhibit lower valued priorities. Why is this the case? What are the benefits?

I'm currently studying about Linux in general and what it is. I see that Linux is a high-performance operating system that breathes life to old hardware. Ubuntu is a distribution of Linux.

But I'm uncertain whether Ubuntu is an embedded system. Embedded systems execute applications without an overhead kernel, and Android is a prime example in the mobile world. Is Ubuntu an embedded system as well?

Whether it is or is not, how does this fact account for the high performance of the system?
