Video memory Fully not detectable

[Daryl Hughes]

when i checked my video memory on my computer it says that it has 256 MB memory which dont has 2x then that. (512MB)
I've tested this with FGLRX (ATI/AMD Card accelerator ) and seems to read it but with out it it will only read half of it

apport information

[Daryl Hughes (zorw2016)]

Got a little more infomation about video cards and Event Engine isn't working got a picture attached of the GPU performance and active
when ya use FGLRX it works but don't with out it seems to be the same with the memory part to

[Daniel Letzeisen (dtl131)]

It's probably recognizing all your memory. See bridgman's explanation here: http://phoronix.com/forums/showthread.php?26231-r600-uses-only-256-mb-video-ram

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Tested this on Kernel 3.15* Latest of date
and kernel 3.16* RC1 newest

Is radeontop saying you only have 256MB RAM or are you only going by the lspci output?

As for the Event Engine issue, that would probably be better if reported directly to radeontop dev(s): https://github.com/clbr/radeontop

for the info that im getting this from im usin command:

sudo lshw -class display

after i put that in it shows alot of code which i cant log and goes way to fast for me to read but 1 of them stays on for a little while and shows
