PS: I just build fbdev from /extras/sources on slackware dvd and it seems
to work now.

Could have fooled me. I see fbdev driver builds in current versions of<br>
Arch, Debian, Fedora, Gentoo, and openSUSE. What distro are you using<br>

<br>
&gt; Question #1) Is it true that fbdev is deprecated and removed in<br>

<br>
Generally people would prefer that new video drivers use the drm driver<br>
infrastructure and not fbdev. In that sense fbdev is &quot;deprecated&quot;, but<br>
not &quot;removed&quot;, it&#39;s still there and works as well as it ever did.<br>
<br>
&gt; Can I still compile it by my self? Is it worth doing in my case?<br>
<br>
You can, but again, I bet your distro has it built already.<br>
