NVIDIA brightness and suspend issues on VAIO

Hello,

I have problems with NVIDIA driver (assuming) and I searched similar topics on forum but still couldn't solved. I'm on ARCH 3.1.5 Xfce, installed nvidia-290 proprietary driver and nvidiabl from AUR. No swap partition and using lightdm. Laptop model is VAIO VPCF132FX, resolution at 1600x900.

  • blank screen when switching to tty1 - tty6 but I can run commands in virtual consoles (tried log in and reboot from tty1 not seeing just typed). I added vga=xxx in grub kernel line and it's changing resolution while booting but switch to ttys still gives blank screen. I think it's happening after started X. If I doesn't start Xfce I can switch.

  • can't resume from suspend. I think it suspends successfully and when try to back it freezes, no inputs from keyboard (tried some shorcuts, numlock, password etc) and blank screen. After few seconds fan reaches at it's loudest and I ended up with 5sec turn off. Is it hardware related issue or kernel (or X lightdm Xfce). Should I use laptop-mode-tools to get suspend work or missing something?

  • if I added

    Option	"RegistryDwords"	"EnableBrightnessControl=1"

    to "Device" section in xorg.conf, keyboard shortcut of brightness and brightness-applet are working. It has 8 level of brightness and only top 3 of them works properly, if it gets lower from there screen blinks few seconds and back to highest brightness. I removed that line from xorg.conf, installed nvidiabl it works great except keyboard shortcut and brightness applet. How do I get shortcut and applet work on Xfce with nvidiabl? Also shortcut is working when numlock is off, is there any chance to work either numlock on or off?
