64-bit 13.10 shows 1GB less RAM than 64-bit 13.04 did

Asked by K7AAY

Multiple 64-bit versions (Kubuntu, Lubuntu and Xubuntu) once installed on my ThinkPad R60 show 3GB of RAM, not the correct 4GB of RAM. Last week with 13.04, I had 4GB of RAM (which matches the BIOS) and this week I have 3GB available.

Here's a biopsy report on the wee beastie, and I surely would appreciate help with the problem.

Linux R60 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux r60

Check how much RAM you give the video chip. If it is separate from system RAM then I suggest you report a bug

Can you help with this problem?
