Acer Veriton N2620G PC flashing like it's on an acid trip!
-
Still trying to figure this out. With no help from Acer. If both working and non-working models use the same graphics controller (still don’t know for sure due to Acer’s lousy documentation.) could the weird display problem be due to the general chipset on the motherboard?
-
If you’ve got one already running some flavor of linux, we can use that to figure out what driver we need to compile into the FOG kernel.
try:
[CODE]lspci -k[/CODE]
or
[CODE]lsmod[/CODE]and look for your graphics card info.

Hi, I got the same problem with Acer Veriton N2620G, though what I tried to install is Ubuntu 12.10, like Hunter had mentioned above, the same symptom was encountered. Some modification were made that made the installation successful with Ubuntu but without the optimal performance. The unit is okay with Debian, no problem at all.
Acer Philippines relayed to us Acer HQ’s (Taiwan) advice:

Finally got what appears to be a definative answer from Acer regarding drivers:

[FONT=Times New Roman][COLOR=#000000]So. Here’s what Acer said the working system has. This leads me to think, perhaps it is a graphics driver problem. [/COLOR][/FONT]

Did you try the suggestion in Art Mendoza’s post?
-
To be honest, I don’t quite understand it. Do I mod the FOG kernel to do that?
-
Yes. You need to compile a custom kernel.
Follow the wiki article and grab the latest stable kernel source, which I think is 3.7.8, or if you are already know the 3.3.3 kernel works with most of your devices, grab the 3.3.3 kernel source.
It’s pretty easy from that point on to compile the kernel, just substitute 3.3.3 for the kernel version anywhere the article says a different one.
You may have to install a few pre-reqs before you can compile: gcc, make, git, libqt3-dev, etc that are listed on the wiki or help site about compiling kernels for your distribution.
-
Can I grab the kernel from the fog machine itself? Where do I get it from?
-
[url]http://fogproject.org/wiki/index.php/Building_a_Custom_Kernel[/url]
Article assumes you have make, wget, and g++ tools already installed.
This is step by step pretty much. You can look at [url=“http://www.kernel.org”]www.kernel.org[/url] to find the latest stable kernel, and get the path you need for the wget command.
I copied the core.config file from the /opt/fog-setup/fog_0.32/fog/kernel directory instead of the kitchensink.config because I know from experience it works better for my environment. But you can try the kitchensink.config first if you want.
-
This is the kernel “bzimage” from the update kernel page, yes? Or is that something else?
-
something else.
-
What are the G++ tools I need?
-
the package is called g++ and gcc are both meta packages in Ubuntu that download all the parts…
-
So far, trying what Art Mendoza suggested hasn’t helped. But maybe I didn’t do it right… Back to the drawing board.
-
When I do:
[CODE]lsmod[/CODE]
under the video result is:
[CODE]video 9463 1 i915[/CODE]
I’m guessing that in the kernel config this would be included in the intel 8xx/9xx line.
One interesting notion, when I tried to compile the kernel the first time (using the kitchensink.config), the resulting bzimage was about 6MB less than the “official” 3.6.9 Core.[url=“/_imported_xf_attachments/0/259_Kernel_Help.PNG?:”]Kernel_Help.PNG[/url]

OK, mess up on my part. I reread Art’s post. It appears to be working now.
Thank You.
