Currently I am using Lubuntu 12.04 desktop installed on my PC. When I play videos, the videos are really slow. It skips frames
I have following PCI devices installed on the system Host bridge : Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 03)
VGA compatible controller : Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03) (prog-if 00 [VGA controller])
xserver-xorg-video-intel and mesa-utils packages are installed. Direct rendering is enabled. It really doesn't matter if it is enabled or not, both the times the videos are slow almost similarly. While looking for a solution I found a page on intel drivers http://manpages.ubuntu.com/manpages/precise/man4/intel.4.html which deals with Intel graphics drivers.
Is there any way changing the VideoRam to higher value can be helpful? Currently AGP Memory is 128 MB and from the above manpage VideoRam will be set to 8M if AGP >=128MB. 82845G has a AGP memory of 128MB. Is there anyway I can increase VideoRam? I have tried ubuntu with AGP Memory 256MB, where videoRam will be set to 24MB by default, the HD videos are also playing smoothly even though the processor is Intel Celron 1.6Ghz.
Is there anything I can do to increase videoram size? or is this because of something else?
A commentor asked me to attach outputs of dmesg, lsmod, lshw and /var/log/kern.log.Here is the output of those commands http://paste.ubuntu.com/1071664/
