[Solved] eeepc 1015pem and uvesafb

zacariaz · 2012-08-20 18:44:26

I all started with me wanted to pass the correct resolution to the kernel, but found that the native resolution wasn't listed. I then looked at 915resolution-static listed on the uvesafb page, but as it wasn't made for my chipset, I wasn't surprised to find that it didn't work. Lastly I simply tried to follow the instructions on the page and am now looking at a very black screen.

After searching the net far and wide I found on forum thread that seemed to explain partially why it didn't work, but to be honest the fix provided seems rather complicated and the initial post is almost 2 years old, so probably not that reliable anyway.

But to get to the point the asus eeepc 1015pem in question utilize the pineview platform and thus the gma 3150 gpu.

Now the question is if anyone can help me achieve my goal or if I should give up right away. I've spend a few hours meddling with this and it has been fun, but I've run out of ideas.

Please remember that I'm perfectly aware that this really isn't a huge issue, but I like a challenge if if serves a purpose and in this case it does, since I don't intent on install an x environment.

Anyway, I'll fix the black screen and hope for a lot of really intelligent replies when I return.

Best regards.

pps. I should remember to mention that I also experience the black screen with supported resolutions other than 1024x600, so I suppose it's possible I've made a mistake, though I really don't see how.

Pineview is supported by the intel driver, so why are you trying to use uvesafb? You don't need to do *anything*, because it all works directly out of the box.

zacariaz · 2012-08-20 18:53:11

well, the only intel driver I know about is for xorg and whatever driver is used out of the box apparently do not support the native resolution of 1024x600.

It is of course quite possible that I'm missing something critical, but never the less...

In any case I'm just playing around, so no harm done.

Not just for xorg, it's a KMS driver, and those handle the console too. And trust me it *does* support the native resolution. My brother has a Pineview netbook, it's not necessary to do anything to get graphics going on it. It just works™.

ok, I'll try at see what I can figure out and the return.

thanks for now.

Just one little notion before I start messing about...

Why does it state on the wiki page regarding Intel that xorg is a Prerequisite? ( https://wiki.archlinux.org/index.php/Intel#Installation )

zacariaz · 2012-08-20 19:10:06

Further reading revealed this fancy little quote: "Note: For use within the console without X, see Uvesafb."

As you can imagine I have in fact seen quite a lot of the uvesafb wiki page. However, is there the possibility that I needed xf86-video-intel too? Because I didn't install that at all...

Gusar · 2012-08-20 19:22:41

No idea why it mentions uvesafb, that's just wrong. And it says xorg is a prerequisite because, well, the entire article is about X.

Let's try this a bit differently: What exactly is your problem, and what exactly is it that you want to do? If you just want the console, you shouldn't need to do anything. If you want X, you need xorg-server, xf86-video-intel, and something that will run in X (the default config tries to start twm and xterm, so install them if you just want to test whether X works). That's it.
Optionally you can put the i915 module into the initramfs so you'll get a high-res console faster, but that's, as mentioned, optional.

well eventually I want to mess around with a lot of framebuffer stuff I suppose. I'm certainly going to install qingy for example, but you're right, it is entirely possible that I have completely misinterpreted something here and that everything, as opposed to what I thought, actually works as intended, despite the correct resolution not being listed anywhere.

So how do I check once and for all if my resolution is in fact 1024*600?

zacariaz · 2012-08-20 19:50:46

So I've been count pixels

I'm quite sure that the width is 1024 as should be because it can fit 128 characters which don't seem likely for a width of 800 and I can say be great confidence that it's not 640.
as for the height, that's another matter, however I've counted 37.5 lines and as the line height seem to be 14px or more... Well, let's just say that 37.5*16 = 600... That's too much of a considered.

Yes, that's how I parse the time

Other that, sorry for me confusing my self and everyone else more than necessary. I shall make sure to mark the thread solved ASAP, though if there is a trick beside counting pixels, please do let me know. Always nice to be sure

Best regards and thanks once again.
