Hello!
I've been Windows user/programmer for years.
Now I'm running dual boot with Ubuntu Linux.
I'd like to try Linux ASM programming.
Can someone show me tutorials for Linux programming and also how do GUI ASM programs on Linux?

Thanks

Ozzy: most native form of doing GUI for linux is programming directly the X server. There are some examples from Feryno on this board.

But programming X server can be painful, so there are few libraries that do it for you.

Most notably, there is GTK. It's C library, you can read few tutorials and try to write examples, it would be mostly welcomed.

Then, there is Qt. This one is C++ library, so you won't go very far with it in assembly.

Third very popular is WxWidgets. It's C++ too, so no go. This one is most portable (all three of them are ported to windows, but this one uses native looks of OS).

I would suggest you to go for GTK.

there is also svgalib and frame buffer graphics these run in the terminal without X11
they may be a better starting point than X11

note on the frame buffer this one needs to be started from with in the kernel at boot time
here is some info on using the frame buffer http://asm.sourceforge.net/articles/fb.html

OH I almost forgot you may have to build a kernel to support the frame buffer depends on your distro

so If I use GTK my asm program's GUI will run on all distros of linux?

You may start here : http://asm.sourceforge.net/

It should but GTK needs to be installed, but it's not unusual at all for anyone to already have it, or be willing to install it to run your program. Gnome uses GTK (Gnome Tool Kit) but you don't need Gnome to run GTK.
