Thread: New laptop - help needed

  1. #1

    Default New laptop - help needed

    I've been using opensuse for quite a while (and linux for maybe 10 years) and had no problems whatsoever with different computers. But now I just got a new laptop - MSI FX420-002US (i3-2310M, Intel HD3000+Radeon HD6470) and this is the first time when I can't use linux normally... I really would like to keep using it, so asking here for your help.

    I can leave without all those fancy buttons this laptop has, but I need some basic functionality, that is using graphic cards and normal battery life.

    - for whatever reason, fan is going on non-stop with much higher speed than it is doing in windows and this leads to 2 major issues:
    1) noise
    2) and what is more important, it drains battery so I cannot get more than 2 hours of battery life compared to >4hrs in Windows. Don't know if this is of help, but when I run sensors it returns me 3 readings: temp1, temp2 and temp3 with first 2 being around 30C and 3rd one is ~70C (while on windows CPU-Z gives me core temperatures of 40-50C for both cores) - maybe this forces fan to speedup?

    - I installed openSUSE 11.4 and it started correctly, using only intel videocard. I can't make Radeon HD6470 work - radeon driver doesn't support this chip and proprietory fglrx gave me something like "cannot load driver - your chipset is not supported". The same actually happened in Windows: I couldn;t update driver with the same error. Is it possible to use switchable graphics at all?


    I would really appreciate if you could help me with those 2 issues!

    Thanks!

    My guess is that temp1 and 2 are the two cores of the cpu, lower than in
    windows. I don't know what is the other one. Video? Disk?

    Yes, a warm temperature means that something is warming it up (using
    electricity to do it), and that the fan has to turn faster to compensate.
    Both things means shorter battery life.

    Find out what the third sensor is for.

    CPU Speed control exists now only in YaST and can have a big impact on power usage and heat generation. Why not do the following, open:

    YaST / Software / Software Management, search on Power and install yast2-power-management. Once done, restart YaST.

    Next:

    YaST / System / System Services (Runlevel), select Expert Mode Bullet at the top left:

    Now:

    Find and highlight pm-profiler and then select the button on the bottom right and Enable the pm-profile Service and answer yes to the added services requested.

    Next:

    Select the button on the bottom left and Start the pm-profiler Servrce. You should get a good start with a 0 error return code.

    Now select the finish button on the bottom right and allow your selections to be saved.

    Now:

    YaST / System / Power Management. You can select from three choices with Power Saving doing what I think you are looking for. It is also possible to upgrade the kernel from 2.6.37 to 2.6.38 which might help even more, if interested.

    Thanks Carlos!
    was wondering myself what this 3rd sensor was for. But have no idea how to find out.

    Thank you James! Didn't think about this option. Made those changes - will see how it goes. Fan is still going fast though... Is there a way to change profiles quicker? I mean not going into YaST?

    Thanks,

    Did you select Powersaving to see if that helps? I do not know of a faster way to run this function, but I will check around to see if this can be run directly.

    I don't have any experience in this myself, but according to Phoronix there were 2 major regressions in the Linux kernel impacting battery life.

    The change from the 2.6.37 to 2.6.38 kernel purportedly had an impact on power management, resulting in an average of 5 to 10% reduced battery life. The earlier change from the 2.6.34 to 2.6.35 kernel had an even larger negative effect on power management and battery life. ... I can't comment on additional features those kernel updates may or may not have provided, but the view of the engineers at Phoronix is upgrading the kernel thus far has had the opposite effect on battery life.

    I started a thread about this subject (which contains the references) here: Possible Power Management regressions in recent Linux kernels ? .... Please don't 'shoot the messenger' ... I'm only posting the above to note there are different views re: kernel upgrades for improved power management.

    Does that laptop have 2 hybrid graphic devices ? If so and if openSUSE is working well, then you are one of the few who seem to be doing well with a hybrid graphic device combination.

    There are a number of users on our forum who have complained about problems with hybrid graphic device setup, and thus far the help threads to assist these users provide no indication of satisfactory resolution in helping these users with their laptop graphics.

    If your laptop has hybrid graphics, and if you had to do anything special, and if you succeeded, I for one would be MOST interested in learning your technique(s). Thanks in advance for any tidbits you can pass on.

    Yes, I did select that. So far not a significant improvement - 2 hrs 30 min vs 4 hrs 20 min according to power-management systems on openSUSE and Windows respectively. 50% of battery was used in a little bit more than 1 hr while on openSUSE (mainly browsing), then I rebooted into windows and worked for almost 3 more hours (watching video)...

    that's a bummer... Anyway, thank you, I'll to look there to find out if there are any options available.
