I have used FC3 and FC5 installations. By default, I donot get the framebuffer devices created. I had to build the kernel v18.104.22.168 with the options to include framebuffer. After installation and restart, I have to manually create the framebuffer devices (mknod /dev/fb0 c 29 0 and so on for 32 devices).
Even after this, I am not able to access the framebuffer device /dev/fb0. On these installations, I am able to change display resolutions to 1024x768 or more for 24bit and 32bit colors.
I tried to install FC2 with default kernel v2.6.5.x. This created the framebuffer devices (0..31) by default. But I was not able to access these devices. However, when I built the kernel v2.6.8.x and restarted, I was able to use the framebuffer device to read/write data.
The problem with FC2 installation is that the display resolution cannot be set for more than 800x600 (24bit color).
Here again I tried to rebuild with v22.214.171.124. There are a whole lot of incompatibilities like GNU libraries (gcc, gmake, etc) with the FC2 installation.
What might be the problem in having framebuffer working properly on a particular Fedora Core installation?
Do you think that it might be a graphics card problem? My card is i810 Intel graphics onboard graphics.
I appreciate if anybody can help me get framebuffer device working properly.
I am currently referring to HOWTOs given below:
... and a couple of other links.
Thanks in advance,
