Enhanced Machine Controller

I just tried to install the LiveCD again after last night leaving me at 
the maroon screen of death and the only thing that got installed from 
LinuxCNC was the docs in english and truetypetracer...

I think something really must be going on. If I had to guess (and I do, as I have no data) I'd suspect that something different happens when the installer finds an internet connection vs. when it doesn't. Perhaps apt is nuking linuxcnc because a dependency is not met. You should have a dpkg/apt log available after the install, and it may contain the smoking gun. Please let us know what you find.

Re: [Emc-users] LiveCD Fails to install LinuxCNC From: John Thornton <bjt128@gm...> - 2012-06-14 10:23 Jepler sorted out that if you have 4Gb of memory and your connected to the internet then ubuntu kindly unloads the real time kernel and subs for a better one. I verified this a few times. 3.2Gb does not have this same problem. I posted the logs yesterday to linuxcnc-dev. On another note what prompted me to reinstall LinuxCNC on my plasma was I thought I broke it somehow trying to "fix" the psychedelic colors in gedit for a ngc file when calling a subroutine file with my pyvcp button gave me an error of "File not open"... which made no sense till I kept trying different things on 3 different machines (after finally getting LinuxCNC installed) until I came to realize what the cryptic error meant. Somewhere there is a check to see if a file is loaded before a subroutine is run and if you don't have a file loaded and it can be a file with just M2 trying to call a sub from MDI fails as well as having a halui mdi entry in your ini file. This was quite difficult to track down as I don't load a splash file in the INI.

Re: [Emc-users] LiveCD Fails to install LinuxCNC From: John Thornton <bjt128@gm...> - 2012-06-14 11:01 I don't know if that is the ultimate solution but it does work and so does popping out one memory chip from the 525.

John, can You explain, why do You use so much of RAM? I put 2 GB in my machines only because I do not have swap partition on SSDs. AFAIK LinuxCNC is happy with 1 GB, so I have another GB just in case. I had Lucid on my parent's PC with 512 MB RAM. It used to freeze up from time to time. Took me a while to realize to look at the usage of RAM and then I realized that I forgot to create swap partition during install (that pc has traditional hdd). -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto

Well, except in odd ball cases like John's where Ubuntu does funky things. I'd rather have too much than not enough memory. You can also use RAM as a fast file system, though it's volatile so I wouldn't want to try and save anything there. Mark

Re: [Emc-users] LiveCD Fails to install LinuxCNC From: John Thornton <bjt128@gm...> - 2012-06-14 11:32 Because there are two slots and that is how much ram that fits is the only reason that I have... no logical reason at all.

Re: [Emc-users] LiveCD Fails to install LinuxCNC From: John Thornton <bjt128@gm...> - 2012-06-14 11:54 IIRC, the ram choices were pretty limited on the 525 to 2 or 4Gb... so to get 3.2 I had to pick 4... sounds plausible anyway, but I doubt that it happened that way.

At least for PCs I think there is no way to get 32bit-only capable system. All the new CPUs are 64 bit and they are backwards compatible with 32 bit, so I am sure that this backwards compatibility will remain, so 32 bit OSes will be there as long as anyone will maintain them. > > /tmp is already in RAM when your system is created.  There's also a > /var/tmp too. > Not really. This the first point in my optimize-for-SSD list: 1. Keep temporary data in RAM # Edit your /etc/fstab file. Add the following lines. tmpfs /var/log tmpfs defaults 0 0 tmpfs /tmp tmpfs defaults 0 0 tmpfs /var/tmp tmpfs defaults 0 0 AFAIK Lucid does not do that by default -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto

[Emc-users] LiveCD Fails to install LinuxCNC From: Schooner <schooner30@ti...> - 2012-06-13 15:51 Hi John Can you check your /var/log/installer directory This sounds very similar to this thread I was involved with http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=9&id=20126 The problem was that ubiquity was re-instating the stock kernel part way through the process and this caused the rtai kernel and all packages that depended upon it (linuxcnc) to be removed. The solution was bizarre but it worked. regards

Good guess, and close. What it seems to be is that if you have an internet connection _and_ more than 3.2GB or RAM then the LiveCD chooses a "better" kernel for you. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto
