Ok this is a thread for Ubuntu 10.04 support.

I was advised that this is not a supported OS but I seem to have ASP 6.1Pro functioning without pain.

Also I just found this bug report from the Chewenater using 10.04 user:
viewtopic.php?t=16563&start=0&postdays= ... ight=linux

...that seems a non fatal problem. So I have good hopes now I know I am not the only one.

My probs:
ASP can't find my web browser. Not sure how to fix this. It means register, help and other browser opening commands are not working.

My second problem is that stylus input seems to slow the whole machine to a crawl. I am using a tablet pc. It is like the stylus is being polled way too often or as if it is not correctly detecting the click and release of the stylus.

Perhaps it is related to what Genete reported on this post for Ubuntu 9.04 (which is a supported distro):
viewtopic.php?t=14769&highlight=linux

The effect of the problem is if I move a bone on the opening sample with the mouse it is fine. If I try it with the stylus it moves slowly pixel by pixel and freezes the machine up until the motion is finished...

ok this is better as bug report thread... (relating to the stylus input problem)

In general, all the tools are extremely slow in my tablet pc if I use the tablet input. They are overall fine if I use the touchpad or a mouse. Plus the pen pressure doesn't work out of the box. I assume that the pressure system that Anime Studio uses is the old one before Ubuntu changed it to be controlled by hal (hardware abstraction layer). The rest of Gnome applications read the inputs from the wacom driver libraries that has evolved at the same speed than the ubuntu modifications. Since Anime Studio directly reads the input from the devices it doesn't read properly the pen pressure with the default ubuntu xorg configuration.
I have pen pressure in Gimp, Inkscape and Synfig which uses the standard wacom devices input libraries and were you can configure from which device (maybe there are more than one input device) you want the pen pressure been taken.
Regarding to the slow response of the tablet input I bet that the script is getting overwhelmed with the amount of information it is receiving from the device and so it slow down the lua scripts a lot.

Hi Genete

I am getting the impression that lack of pen pressure is not a major issue for AS.

If you follow that link and instructions exactly should fix tablet slowness for Ubuntu 10.04. I spend some time acheiving this result because I noticed when I use my tablet eraser AS goes fast but not with the stylus. I mean a genuinely nice speed on an old tablet (lenovo X60) with a slow 1.2GHz Core Solo chip.

I have spend a second day on this problem and it seems Ubuntu tablet-pc support is in a bit of chaos with all the HAL/udev/x transitions going on and some sort of fork between serial and usb tablet code going on. The way I posted on the link is the one and only way I could get it working.

Also it only works with exactly those device names/identifiers. So what I am achieving by my 'fix' is pretty much unknown.

And for some reason with that solution tablet sensor screen rotation is broken. xsetwacom set stylus rotate CW causes an X server crash.

They seem to be working hard on all these issues but unless you want a lot of messing around the solution will be, at best, in Ubuntu 10.10, not until October, or some other distro. By that time who knows what else will have broken in AS.

So now I have to boot with/without my xorg.conf depending whether I want to run AS or have a screen I can rotate. Sheesh... So I am definitely curious if we can find another way to address this.

Tks for the Synfig work by the way. Playing with AS I am getting a much better sense of the sort of polish which Synfig could achieve in time.

Hi gravly,
yes, probably tweaking the xorg.conf file you could make AS pen pressure but I'm bored to do that in the past. I ended with a ton of copies of xorg.conf file and spent a lot of time in text mode copying and restoring a "working one". Ubuntu is getting a lot of mess with the extended device settings support and I just leave it as it is by default. Most of native Gnome applications uses gtk interface for the extended input devices (wacom or not) so I won't continue editing the xorg.conf for a particular application. In general is the application who should adapt itself for the supported operating system. In the linux case it is more complex due to the great amount of options to access to the input devices.
You're welcome about the Synfig work. We are doing our best to make it a better application each day.
