Hello Brendan, I found meanwhile many other posts, that say this HP Compaq nx6325 (AMD Sempron 1,8 Ghz) Notebook cannot cope with the full 4 GB RAM in Linux and in Windows. They can be installed, but only 3 GB will be used and about 2,8 GB RAM are shown then by the OS or by Windows.
ATI-Drivers didn't work until now with natty on HP nx6325 after several trials to install them. Therefore the Catalyst Control Center did not find an ATI-driver. The newest proprietary ATI-Linux-Radeon-Driver did not work. The oldest available version could not identify the new Natty Ubuntu. Proposals from > http://wiki.ubuntuusers.de/grafikkarten/ati/fglrx/Manuelle_Treiberinstallation did not work. The terminal 'said', there is no way to find the (installed) proprietary fglrx graphic driver and graphic-RAM. The proprietary driver will also not improve the graphics significantly, because 3D-graphics are not supported by the Sempron 1,8 Ghz version of HP nx6325. I would even recommend "Gnome without graphical effects" as desktop on this notebook, to avoid a partly not full working display. I did ask HP too now and did not get any answer after three days. The newest and last BIOS without memory remapping for HP nx6325 is from 2007. The more positive is to use Ubuntu on this system to make it fast, cheap and comfortable. I also tested and later uninstalled fglrx-packages with Synaptics after problems with the display. The onboard-graphic-card (ATI Radeon Mobile XPRESS 200M) is to weak for the fglrx-drivers. In Ubuntu works the by natty installed xserver-xorg-video-radeon driver by Ubuntu pretty well: > This package provides the 'radeon' driver for the AMD/ATI Radeon, FireGL, > FireMV, FirePro and FireStream series. > > Note that this is not the same as the ATI-provided, binary-only, 'fglrx' > driver, which provides additional 3D functionality for some newer Radeon > cards, but is not supported. > > More information about X.Org can be found at: > <URL:http://www.X.org> > > This package is built from the X.org xf86-video-ati driver module. Saying the Radeon xpress 200M would take the 1,2 GB RAM must be wrong. Original the notebook had only 512MB RAM. ATI Radeon xpress 200M uses 128MB memory. Probably the HP_nx6323-Sempron-system as a whole is simply not capable to use 4 GB RAM. HP may explain why, but did not answer to my question. They may think, the question is to old and out of date. The better is it, to pimpup this notebook with the new Ubuntu 11.04 than to use further Windows XP with ours of de-fragmentation and several security programmes that slow down the PC. Even the Acrobat Reader with its very long installation is not necessary in Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/812499 Title: Just 2,8 of 4 GB RAM shown by Ubuntu.
