New Xorg modesetting drivers

January 15, 2013 — BarryK
aarf posted to this blog about xf86-video-modesetting:

This is an un-accelerated Xorg driver for kernel video drivers that support Kernel Mode Setting (KMS). It seems, can be used as an alternative to xf86-video-vesa, xf86-video-fbdev, or the hardware-specific driver (ex: xf86-video-nouveau).
Note, Debian/Ubuntu name these differently, for example 'xserver-xorg-video-nouveau'.

While looking for further info on xf86-video-modesetting, I came across 'xf86-video-armsoc':

As I understand it, xf86-video-modesetting is generic, and will work with any kernel KMS video driver, including those used in ARM SoCs.
xf86-video-armsoc works with MaliT6xx GPUs and provides some 2D acceleration.
There is also the Lima project for Mali 400 GPUs, which is completely open source.
It seems that all of these are works-in-progress.

Cedarview (and related Poulsbo grphics chips.. Intel atom) seem to require the modesetting driver since 3.3 series kernels. I have had this problem with the PAE slacko (k3.4.17) and pemasu has it with k3.7.2 latest upup. Modesetting xorg driver conflicts severely with my nvidia card GeForce 8400 GS and I put it in the drivers-alternate location in slacko-5.4, however, xorgwizard can't handle it. It's a simple fix for that. I also attenpted to add some code to xorgwizard-automatic to detect a one of the offending cards and move the modesetting driver to /usr/lib/xorg/modules/drivers/ such that it has a chance of being auto loaded. Here are the hacked scripts, tarballed but in package structure: Also, [b]tempestuous[/b] has a forum thread addressing some of these issues with slacko-5.3.3 and 5.4 and has had a few users test, 1 giving good feedback. It was with this info I was able to come up with my rudimentary hacks, which probably need more tests, such as, if the gma-500 module is loaded. NOTE: the server is a Puppy Slacko server (at home) running hiawatha-8.6.. please don't hit it too hard! Else I'll lose my bandwith.. :worried: [:n_n:]

""While looking for further info on xf86-video-modesetting, I came across 'xf86-video-armsoc':" if this was in the mele image i think my aurora II tablet might then work. it has 7 inch 1024x600 screen and refuses to boot with the multitude of non-android images i have tried. the slacko54 i have been using is with a save file from slacko533. dont know if this contributes to me not having problems. except upgrading the layered file system at every boot, and removal of desktop icon modifications, but it is not a big problem because i keep using it.
