Framebuffer or Xvesa problem on DE2i-150 board

[khalils@kth.se]

Hi
I try to run TC on a DE2i-150 Terasic board. I tried different TC versions. My problem is that screen is not refreshing smoothly, for example when I move the mouse it mess the screen and it takes some times to clean the mouse movement trace. It is like that when I open a window and move it on the screen. Can somebody help me to find the problem. Is it because of bufferer or Xvesa. Do I need to pass an option in boot time?

What version of tc are you using?

Xvesa and Xfbdev are separate extensions, which one are you trying to use?

Hi
I use Tc 5.2. I have tried some older versions as well. I just use default boot. The only difference is that I use my own BIOS not default which has no ACPI support. Processor is  an Intel Atom N2600 with NM10 chipset (Cedar Trail). On-chip graphic SGX545.

There is no default X driver You are loading one.
Which are you loading?
Xvesa?
Xorg?
Xfbdev?

I would suggest trying Core with the stock BIOS to see if your BIOS is the problem.

Thanks for reply
I guess its xvesa since I haven’t changed any setting. I got .iso file from homepage and made a boot-able USB from it. I tried different resolutions in xsetup.sh but still have that problem. 
I tried  pupy linux on the same board . It has not this problem, I guess it uses Xorg but pupy is big and is slow to boot.  TinyCore boots super fast (2-3 seconds) and is small.

Sorry if my question looks basic, I am not that experienced in Linux. But is it possible to create a custom TinyCore package with for example LXDE?  Is there an automated tool to customize and generate tinycore.gz package?

Please read the book and the articles referenced on the top of the home page.
Every installation of Core is custom.  You pick the extensions to load at boot.

PowerVR graphics is known to be poorly supported, IMHO you might want to look into optimizing graphics before installing a heavier graphical environment like lxde.
