[Bug 312756] Re: support graphics card hot switch
Hi, I tried that deb package but it complained about not finding rt73 module. I tried to install that module, but had no luck. So I removed the module, reactivated the other one (nvidia off). I removed everything about nvidia using synaptic, and when I have booted up this morning... I have desktop effects Looking at glxinfo and xorg.log it seems that it is using the Intel GMA with MESA. So at least I have a kind of decent performance with desktop effects and reduced battery consumption. Shame not to be able to use the nvidia card, but at least the system is more usable now. -- support graphics card hot switch https://bugs.launchpad.net/bugs/312756 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@rmartinez my comments here are in the public domain ;) feel free to copy them, I'm glad they were useful. I agree we all should do the same and write to the manufacturer support team. Let's wait a little for Asus to answer, but if they don't or their answer is the same, I think it could be a good idea to create some website/blog (or better use Albert Vilella's blog on the subject if he wants) to give some advice to potential buyers that want to use linux on hybrid graphics laptops. Something like a list of manufacturers with the kind of support they have (BIOS settings, public specs, drivers, etc). That way people will have more information on what to buy (and what to NOT buy) if they want to use linux. -- support graphics card hot switch https://bugs.launchpad.net/bugs/312756 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 312756] Re: support graphics card hot switch
@Alexandre I can't still measure how much battery lasts when the nvidia card is disabled, but from what I've read the power consumption is reduced by 5w to 10w. Can you tell me something more about the solution you use for cold switching (acpi_osi)? @Fabián, I've got a first answer from Asus support. I wrote them both in Spanish and English, got an answer in Spanish so I will translate it into English: QUOTE START: Dear customer: We can't give you support for an operating system change to other than the one provided with the laptop. You can find at our web site all the drivers that have been released up to the moment for different operating systems, in the event that you wished to make an operating system change under your own supervision. Nevertheless, we are going to pass your request just in case it could be added in the future. Thanks. QUOTE END I've answered them that they should *read* my message because I'm not asking for that kind of support, and clearly explaining (again) my two requests: 1. That they release a BIOS that lets their customers select the video mode (hybrid, intel, nvidia) 2. That they publish specs/apis/etc so the linux community can create the appropriate patches/drivers I also remembered them that I am their customer, and that I've bought a laptop, not an operating system from Microsoft (I've been forced to do so). Lets see what they say, but I have little hope... -- support graphics card hot switch https://bugs.launchpad.net/bugs/312756 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@toni Hi, the way to kill (disable) the nvidia card is through a contributed kernel module: http://linux-hybrid-graphics.blogspot.com/2009/12/solution-to-switch-off-nvidia-card-in.html I will check again if a BIOS update is available for my Asus UL50VT, but there was no option to change between cards or modes as your Lenovo has :( The BIOS should have such an option, it is not like choosing at boot time or like switching it live, but will do the trick in the mean time. -- support graphics card hot switch https://bugs.launchpad.net/bugs/312756 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 312756] Re: support graphics card hot switch
@Fabián, I apologize if I gave the impression of complaining about the effort of the linux community, but I don't think that is the case. If you carefully read my messages you will no doubt understand that I was complaining about *this issue being declined for karmic and lucid*. I appreciate all the effort, linux has performed a giant leap forward and Ubuntu specially is the best option in my opinion. You can read at the asus forum the actual status of this (which is no answer on asus or nvidia side): http://vip.asus.com/forum/view.aspx?id=20091224184305125board_id=3model=UL50VTpage=1SLanguage=en-us I've also submitted my complaint, yes this is a real complaint, to asus trough their support form requesting they give the linux community the specs and tools needed and at the very least that they release a BIOS upgrade to let us choose the video mode.

[Bug 312756] Re: support graphics card hot switch
Hi, I didn't see the comment by Timo requesting no more DSDT.dsl attachments. But is very disappointing for me seeing this as declined for Karmic and also for Lucid (which means that an official solution will not be available *at least* until October 2010). After many years of using Ubuntu only I had to use the included Windows 7 since battery lasts 10 hours (one of the main reasons I purchased this laptop) and also I don't have any kind of visual effects on my desktop (which means I've lost the transparency effect that was so useful for me). It should not be considered wishlist as it will surely drive users away from Ubuntu :( Hot swapping cards is not really the important thing, I would really be happy if I could select that at boot time or before the x-session is started. By killing the nvidia card I now have a little more battery, but it is not enough and not a solution. -- support graphics card hot switch https://bugs.launchpad.net/bugs/312756 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
