dCore - ub-dCore

[Onyarian]

Hi Jason,

I am very impressed with ub-dCore, after configure it to my liking, I check the amount of available software and through mergesce I have made 4 large sce's (Desktop, work, multimedia, utils). Fantastic!

Two desktops pc's have nvidia card and work properly, but two laptops instead I could not configure graphically, I only get 800x600 instead of 1024x600 and it seems the problem has to do with the i915 being the last line of dmesg:

i915: Unknown symbol i2c_bit_algo (err 0)

This problem is common to dCore and ub-dCore.

repositories to /opt/debextra:
http://us.archive.ubuntu.com/ubuntu saucy multiverse
http://archive.ubuntu.com/ubuntu saucy universe
http://archive.canonical.com/ precise partner

Another thing, at boot, between loading extensions and loading mydata.tgz there seems to be some errors which refer to
"udevd[87]: IMPORT{builtit}: 'hwdb' unknown    /lib/udev/rules.d/75-tty-descriptions.rules:11"  and many others like this

Finally, seems that in the control panel in dCore the TcWbarConf button is inactivated, in ub-dCore is OK.

Many Thanks for all this work!

Hi Onyarian,
My laptop has a Nvidia Geoforce 8200m and it is from around 2009 and it works ok but it does not use i915.  But I will look into it and the other things.
Thanks!

My mistake in explaining:
the two laptops don't have nvidia cards (only the desktops pc's), the laptops have agpgart-intel, and with tc5.x they utilize the i915 driver and have the correct resolution, but in ub-dCore and dCore don't.

Onyarian,

I may have encountered the same i915 / i2c problem.

I'm running dCore on an NC10 netbook and I wanted to try it with Xorg. The NC10 has an Intel 945 chip and to get 1024x600 under Xorg it needs the xserver-xorg-video-intel driver and the i915 module, and it turns out that i915 needs i2c to also be loaded. (Maybe it's an i915 dependency that's been missed?) You'll find from '$ searchprebuilt i2c' that there are two versions of i2c in the prebuilt area: i2c-3.8.10-tinycore and i2c-3.8.13-tinycore.I ran '$ importsce -b i2c' and selected the 3.8.13 version to match the kernel and that has fixed the problem - i915 loads, and Xorg uses the intel driver and sets 1024x600 for the NC10 screen.

Can't help with your other questions, I'm a beginner with dCore (first post - hope I've done it right).

ChrisJ -
Thanks for that observation.  I had left the 3.8.10 modules in the prebuilt area as part of the transition to 3.8.13, but since only the current release of dCore is supported or even advised I will remove the 3.8.10 modules to prevent possible confusion.

ChrisJ,

Thank you for your help, but after importsce i2c-3.8.13-tinycore and xserver-xorg-video-intel and put they in sceboot.lst when I reboot it runs like before with 800x600 resolution. The error in dmesg is the same about i2c, seems perhaps another thing?

Re tcWbarConf:
I see that ub-dCore shows it in cpanel but dCore does not.  I looked at the cpanel code and it looks for the tc-wbarconf binary and then shows the button.  Should work in both, it is in the path of both dCore and ub-dCore but does not show in dCore.  I will keep looking for a solution, though it should just work in both.

Hi,

I  have substitute xorg-all with xorg-intel with the same resuts.

Onyarian,

Re-import graphics-3.8.13-tinycore again, I forgot to include the i2c-3.8.13-tinycore package as a dependency.  Hopefully this fixes it, my bad if so.

[Onyarian]

Fine Jason!

That was it! Now I have the 1024x600 resolution in the laptops.

Thanks!
