Dear all, I totally agree to the Jan point of view (see previous post Re: [Sony- vaio-z-series] Sony Vaio Z and VirtualBox) I also found as a reader of the mailist precious and valuable information to get my own vaio VPC-Z12L9 working with the distribution Ubuntu 10.04.
And since I found a way to work Intel card and nvidia card with glx together and as I never found it before in the net (but may be I did not search well...), I take the time to explain how. It may be help somebody else. First thanks you for Adam and all of you ! The Adam's kernel 2.6.36.0 is working for my laptop. I have kept this option linux16 and initrd16 (instead of linux and initrd) in the file /etc/grub.d/10_linux and GRUB_CMDLINE_LINUX_DEFAULT="i8042.reset i8042.nomux i8042.nopnp i8042.noloop acpi_osi=\"!Windows 2006\" acpi_backlight=vendor" in the grub option (/etc/default/grub and update-grub) I do not know if it is needed, but I had sometimes no keyboard working after the boot without these modifications, even with the new kernel 2.6.36-vaioz (it is strange since I read this problem was fixed ?) Now,it seems to work correctly everytime (but I have not so much retrospect to be sure of that, since I made the modification since a very few time,...) As soon as I install the Adam's kernel 2.6.36.0, the Intel card is now working. But, when I install the nvidia driver, problems are rising... and the intel card could not find glx any more... After some tests, I even can not install the current nvidia driver : dpkg: error processing nvidia-current (--configure): subprocess installed post-installation script returned error exit status 10 It seems there are two problems: 1. the problem is that the nvidia driver modify (I don't know where the paths of the ModulePath implicitely) extract of \var\log\Xorg.0.log: "(==) ModulePath set to "/usr/lib/xorg/extra- modules,/usr/lib/xorg/modules" " As a consequence, the intel driver try to use glx library of nvidia in the stamina mode. 2. it seems that only the more recent nvidia driver is working with the kernel 2.6.36. In fact, this is the only one I was able to install after installing the Adam's kernel (see http://forum.ubuntu- fr.org/viewtopic.php?id=425047). My solution to get both working is as follows: - install the Adam's 2.6.36-vaioz kernel (and perharps the linux-source https://launchpad.net/ubuntu/natty/amd64/linux-source-2.6.36/2.6.36-1.7 : I try it to see if it solved the problem of installing the current driver nvidia available directly in Ubuntu 10.04, so I don't known if it is really required to install the nvidia 256.53 driver ...) - Remove the package nvidia-current, nvidia-setting - Reinstall the package xserver-xorg-video-intel (I do not know if it is really needed) - Install the nvidia 256.53 driver: http://dl.dropbox.com/u/737114/vpcs11e7e/nvidia- current_256.53-0ubuntu3_amd64.deb (see http://forum.ubuntu-fr.org/viewtopic.php?id=425047) NB: problem of dependency occurs when I try to install nvidia-setting 256.53 , but I install the current one of the distribution Ubuntu 10.04, and it seems ok. - Then, get the following command: sudo mv /usr/lib/nvidia-current/xorg /usr/lib/nvidia-current/xorg_speed sudo mkdir /usr/lib/nvidia-current/xorg_stamina sudo rm -rf xorg Then I modify the rc.local file provided by Adam: BLUETOOTH=0 WWAN=0 [ "$(uname -r)" = "2.6.28.10-vaioz" ] && reboot [ -x /etc/init.d/kdm ] && DM="service kdm start" || DM="service gdm start" if [ "$(uname -r)" = "2.6.35-rc6-vaioz" -o "$(uname -r)" = "2.6.35-vaioz" -o "$(uname -r)" = "2.6.36-rc3-vaioz" -o "$(uname -r)" = "2.6.36-0-vaioz" ] then if [ "$(cat /sys/devices/platform/sony-laptop/speed_stamina)" = "stamina" ] then rm -rf /usr/lib/nvidia-current/xorg ln -sf /usr/lib/nvidia-current/xorg_stamina /usr/lib /nvidia-current/xorg if [ -f /etc/X11/xorg.conf ] then if grep "\<nvidia\>" /etc/X11/xorg.conf 2>/dev/null >/dev/null then [ ! -f /etc/X11/xorg.conf.nvidia ] && mv /etc/X11/xorg.conf /etc/X11/xorg.conf.nvidia || rm /etc/X11/xorg.conf fi eval $DM restart fi sleep 3 echo 52 >/proc/acpi/video/GFX0/LCD/brightness else # speed rm -rf /usr/lib/nvidia-current/xorg ln -sf /usr/lib/nvidia-current/xorg_speed /usr/lib/nvidia- current/xorg [ ! -f "/etc/X11/xorg.conf" -a -f "/etc/X11/xorg.conf.nvidia" ] && cp /etc/X11/xorg.conf.nvidia /etc/X11/xorg.conf && eval $DM restart fi fi for i in /sys/class/rfkill/* do grep bluetooth $i/name 2>/dev/null >/dev/null && echo $BLUETOOTH >$i/state grep wwan $i/name 2>/dev/null >/dev/null && echo $WWAN >$i/state done So I add the following lines : for stamina mode rm -rf /usr/lib/nvidia-current/xorg ln -sf /usr/lib/nvidia-current/xorg_stamina /usr/lib/nvidia- current/xorg for speed mode rm -rf /usr/lib/nvidia-current/xorg ln -sf /usr/lib/nvidia-current/xorg_speed /usr/lib/nvidia- current/xorg As a consequence: - when booting in stamina mode, /usr/lib/nvidia-current/xorg remains empty and the system use the Intel glx library located in /usr/lib/xorg/modules (since ModulePath set to "/usr/lib/xorg/extra- modules,/usr/lib/xorg/modules") - when booting in speed mode, /usr/lib/nvidia-current/xorg is the right one for nvidia Finally, stamina mode and speed mode (unfortunately always by booting first with the old kernel...) are working. One problem is remaining: when I boot from the intel to the nvidia card, I need to restart the X server (Alt+Imp Sys+k) to have the right resolution. Here is my own contribution... The solution is not very clean... but it seems to work. Perhaps someone has a clever solution: if so, let me know ! Warning and question: "Suspend" gives me a black screen when I reactivate it, whatever the mode (stamina or speed). Is it normal ? Another question: how to make the keyboard backlight working ?
