Sudo chmod +x /etc/pm/sleep.d/10_disable_radeon
# Action script ensures that discrete graphics card is disabled after Sudo vi /etc/pm/sleep.d/10_disable_radeon (not sure this is needed, but it does not hurt and does not take ant time)

Install so it runs at resume from suspend We also make sure bluetooth is disabled on boot hrer.Įcho OFF > /sys/kernel/debug/vgaswitcheroo/switch It is included by default in Ubuntu 12.04, no need to install anything Disable (power off) Radeon discrete graphics at all times, and power of bluetooth on boot. "ACPI _OSC control for PCIe not granted, disabling ASPM" Pcie_aspm=force does not work btw, if anyone can solve this that would be benefitial. GRUB_CMDLINE_LINUX_DEFAULT="quite splash i915.i915_enable_fbc=1 i915.i915_enable_rc6=1 pcie_aspm=force" Make sure Intel powersaving features are enabledĪdd some items to the kernel boot parameters, use the following line

I also added an instruction how to enable TRIM support if you are using an SSD, and also how to re-enable hibernate in Ubuntu 12.04 (precise). In reality I am a developer, and with some things open and doing some real work, power consumption is between 15 and 30W, giving battery times of say 2-3 hours. This should give a standard battery life between 4-5 hours using the built in 52170mWh battery. With the settings distilled from Ubuntu forums on vaio S compatibility everything works nice and I get the following results.īattery drain between 950 mW when idling and doing light work (like writing this). I use only the Stamina (Integrated Intel graphics) mode of the Vaio, and want Speed (Discrete ATI graphics) to be disabled at all times.īy default the ATI card is powered on even in Stamina mode (the physical switch does not physically power of the ATI graphics), so when booting Ubuntu the first time fans will be always on until you manage to power of the ATI card. Powersaving is the area where GNU/Linux, by default, is not as good as the Mac, and requires some technical tweaking. Using the Vaio the only thing that needs attention is the switchable graphics, and powersaving features. I used wired network during install, but connected to wifi ince installed.
Using 12.04 everything works out of the box, trackpad (including two finger scrolling), wireless, screen, suspend and resume. It is not hung though, so just enter your password in the blank screen and it boots.

The alternate installer completed without any glitches, and boots me directly into Ubuntu.Ī minor gotcha is that most times, but not always, I get a blank screen instead of the boot password screen (to unlock full disk encryption). I used the alternate installer in order to get full disk encryption. Extremely nice chassis, but overheats and throttles the CPU very easily. Update: Due to inadequate cooling I would not buy this machine again. Installing Ubuntu 12.04, precise pangolin from USB works like a charm, no issues. SSD, it is very light and has good screen and keyboard. It is easy to replace an existing HDD with an When blocking the air intake with your leg the machine overheats and throttles the CPU to a crawl. The air intake fr cooling is located under the machine, exactly where your leg is if you have the laptop in your lap. I have also found a weak point of the laptop. ASPM does not seem to work anyhow and the i915 parameters are enabled by default in the kernel. Update Ubuntu 12.04: In Ubuntu 12.04 no kernel parameters are needed. With the above I can really get 4+ hours out of the battery, stable through suspend/resume cycles.
This have some new power saving improvement. Otherwise it will be re-activated after suspend/resume so power consumption will be high after resume. This enables me to permanently disable the Radeon in BIOS.

I've tried with the AMD Radeon Software Support for Legacy Graphics Products for HD 7000 series from here īut it actually gets worse because after installing and rebooting my computer I get a "No AMD graphics driver is installed or the AMD driver is not functioning properly ".Using Ubuntu 12.10 I have changed my approach a little bit.
Sony vaio update bios with switchable graphics drivers#
I've tried uninstalling the drivers provided by Vaio and install the ones from AMD's website but I'm really confused about my graphics model being 7570M / 7670M. I've checked a game or application's video setting after doing this, and I always see the Intel graphics card, not the AMD one. However, this doesn't seem to apply at all. I have installed the updates for this graphic card directly from Vaio Update and I have Catalyst Control Center installed and I know I can configure the switchable graphics settings here by adding the aplication exe file and selecting High Performance as graphics setting. I've been searching information about this problem and I've tried many solutions but I just can't make it work.īut it seems my computer never uses the AMD graphics.
