Re: [GTALUG] UEFI bios/firmware

Hello LenThank you for your help.In at least 3 computers I have come across, that has this option grayed out. As shown in pic1 of that link you supplied. So it is not accessible. Every link I came across, basicly had the same solution you described. There for those three computers can not have a true format done. All three have corrupted hinden partions. Putting a new hard drive will not help either. New mother boards would help.Cheers Abby Sent from my Samsung device -------- Original message -------- From: Lennart Sorensen <lsorense(a)csclub.uwaterloo.ca> Date: 08-11-2015 10:25 (GMT-05:00) To: GTALUG Talk <talk(a)gtalug.org> Subject: Re: [GTALUG] UEFI bios/firmware On Tue, Aug 11, 2015 at 12:39:02AM +0200, Abby Bassie-Cripps wrote: > <html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div> > <div>Hello Len</div> > > <div> </div> > > <div>That was very informative, thank you.</div> > > <div> </div> > > <div>For an update, the main computer is question is a toshiba satellite with win 8.1.

Other than the simple out dated method that we all know about?</div> Well from what I can find the process is: When you see Toshiba logo, hit F2, then you should be in the UEFI (BIOS) settings. Under security tab there should be an option for 'secure boot' which you want to set to disabled. If you want to keep windows working, that should be all you change, and then you should be able to install linux as long as the distribution is new enough to support UEFI booting. If you don't want to keep windows and you want to use an older style distribution that does not do UEFI booting, then you have to also find the "CSM boot" setting (under advanced/system settings) and turn that on. That will break booting windows 8.1 on the machine though. I would personally stick with UEFI booting these days. https://aps2.toshiba-tro.de/kb0/TSB2B03F30002R01.htm -- Len Sorensen --- Talk Mailing List talk(a)gtalug.org http://gtalug.org/mailman/listinfo/talk

QEMU and GDB debugging a kernel module
by Aruna Hewapathirane 10 Sep '15

10 Sep '15

Hi everyone, I am able to run qemu and get the *.iso files to boot fine. The qemu image works as well. But for the life of me I simply cannot get gdb to trigger when I set a break point in my kernel module ? I had trouble on my Debian 64bit, gdb complained saying "remote g packet too long" so I patched the remote.c file in gdb and things seemed okay but I am not sure if this did not introduce more bugs. And qemu wouldn't drop me to a shell but hung saying cannot find /bin/init.. So, to double check I ran Ubuntu-MATE 32 bit and all seemed well. But it still will not trigger gdb on my kernel module's break point. Has anyone ever used qemu and gdb ? If so has anyone successfully debugged a module ? I would be very thankful if someone can show me the 'specific' steps to follow to get this going. Documentation in the public domain is sparse and am yet to find something that gives a detailed breakdown of the steps and process. Thank's - Aruna

How to install Intel HD Graphics driver?
by William Park 31 Aug '15

31 Aug '15

For NVidia cards, I just download/install NVIDIA-Linux-x86_64-aaa.bb-no-compat32.run It's one file, and it's easy. To run mplayer with VDPAU, I just set vo=vdpau in the configuration file. I assume it's the same for AMD cards. I don't have AMD cards, so don't know. For those with Intel HD Graphics, how do you download/install driver? I went to Intel site, and it's utterly confusing. I just want Intel's driver, so I can try out VAAPI. -- William

Computer wierdness
by o1bigtenor 31 Aug '15

31 Aug '15

Greetings I don't know what's going on but this is weird! System has been running Debian 8 with things going good (raid mounts so so when saving a file after a reboot all I need to do is click on the listed array give the root password and bob's your uncle). (Its a uefi setup) Well this morning - - - fdisk -l shows the array its not mounted the command I used to use for mounting in Debian 7 no longer works so - - - - any suggestions? TIA Dee

Hello mailing list . . . This is my first post so be gentle. Most of the traffic here is way above my 'pay grade' so I just sit back and read. I have learned a lot, more than a forum. Thank You. The reason for my post is that I am moving soon and must downsize. I have a few things to give away to an educational or charitable organisation but anything other than a commercial operation in keeping with the 'free and open source philosophy' model. Over the past forty years or so I have accumulated an awful lot of electronics (now surplus!), approximately five large plastic containers full of stuff. It runs from cables (RCA, phono, USB, HDMI, SATA) (dozens), wall power supplies (110 volt USB and proprietory) (dozens), computer speakers, headphones, ear buds, USB hubs (powered and not) and even a seventies SCSI cable. I have also three LED monitors (working). In its new days there were many thousands of dollars worth of wire and plastic. It would be a shame for it to go to the local electronics recycling centre on the 19th of September where it may end up. Any offers? I am located about an hour away from Toronto. Would request you come to me. I suggest an SUV or pickup truck. For free, for any audiophiles in the audience, I have two custom built (by me) 5/4 inch solid teak speaker enclosures with three English KEF speakers, a tuned port, and 150 watt three way crossovers minus the front grills. Better get them quickly my cat has found the baffle material and is slowly removing it through the tuned port! They weigh about 20 / 25 kilograms apiece. Any offers? I would like to see them go to a good home and not a transit point to another owner, i.e. re-gifting or selling. These are not for a hand held unit but a powerful audio amplifier or receiver. I probably could throw in a Sony 300 watt receiver. I will not need it after the speakers go. Let me know. Thanks. Paul

On the information prowl
by o1bigtenor 25 Aug '15

25 Aug '15

Greetings I am in need of learning how to setup Apache2, Postgresql, NFS at the same time as I am setting up my NAS box running OpenMediaVault. OMV looks very impressive but with these plugins (and on the sides) there is a tremendous amount that needs to be setup and if its not right - - - well let's just say things are interesting. I have found over the years that man pages and tech docs for Linux, GNU and the like are written for those that really do know what they are doing and merely need a reminder to remember how to EXACTLY write something or set that something up so that a desired result happens. Now to the rest of us who use these tools and have not spent years memorizing C, C++, C#, Python, perl, sql are don't consider these our mother tongue the docs are most often less than useful and too many times less than comprehensible (one of the biggest lacks is examples of good and bad usage of commands). I have learnt my way around certain things and have almost gotten comfortable doing things 'under the hood' but being faced with all of the first paragraph (adding in remote server VirtualBox vms at the very least) is a wee bit daunting. Have found official docs but these assume a lot and as soon as there is something that doesn't work exactly as expected - - - well - - - I'm supposed to know how to modify things (by osmosis I think!). Does anyone out there have suggestion(s) on how to guides for setup, modification and learning at least the first 3 listed? I would be very grateful to find (have already spent many hours looking for how to do things using duckduck) some straightforward guides. When I try to look for something specific like Apache2.2 - - - well all too often its for 2.0 or 2.4 or its 8 years old and nothing in Debian 8 is even similar (different file names for example). I have been trying to keep a log enumerating what I am doing so that hopefully my experiences will be useful for some for at least a short while. TIA Dee

NetworkManager scans wireless every 2min -- solution (finally)
by William Park 20 Aug '15

20 Aug '15

My wireless connection crawls for 20sec every 2min. NetworkManager was scanning my wireless network every 2min (iwevent says so). The problem is that the scan lasts 20sec, and during that 20sec, I get the following dmesg messages: ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 2 failed to flush and my connection crawls. The card is Linksys WMP600N (rt2800pci). I tried different kernels, different driver settings, different NetworkManager configurations, etc. Since it's the only wireless card I have, I couldn't try different card and didn't feel like buying another. Finally, an accidental click led me to a solution: To prevent NetworkManager from scanning, set BSSID to the MAC address of access point. -- William
