So, the problem can be summarised as follows: Login using ‘graphical boot’ (runlevel 5) and KDM – everything works correctly. Login using ‘multi-user boot’ (runlevel 3) and then use # startx to run KDE – USB disk mounts fail with “… Not Authorized” I use a non-graphical login (runlevel 3) and then run # startx, as this … Continue reading →
After all the Pi excitement, back to (relative) normality.. I upgraded my main (x86_64) systems to Fedora 17, using YUM, as usual.. I have found that using the DVD is messy, and sometimes leaves the system in a ‘hybrid’ state, and then the DVD versions of many packages need to be updated, in any case! Compared to … Continue reading →
After many fruitless attempts to cobble together a working USB hub setup for the Raspberry Pi, I came to the conclusion – after trying all the USB/mains power adapters I had (from various phones and other accessories), that the power supply made a significant difference to the behaviour of the Pi.. With some adapters, I had to … Continue reading →
Thought I would try a couple more options, just in case.. First, I confirmed that the USB sound card works connected directly to one of the Pi USB ports (using a USB extension cable): usb 1-1.2: new full speed USB device number 13 using dwc_otg usb 1-1.2: New USB device found, idVendor=0d8c, idProduct=000c usb 1-1.2: New USB … Continue reading →
Another option I just tried turned nasty very quickly… I wondered what would happen if all external USB devices were connected via the (powered) hub, but the answer was soon apparent: usb 1-1.3.1.1: reset low speed USB device number 6 using dwc_otg usb 1-1.3.1.2: reset full speed USB device number 7 using dwc_otg INFO:: periodic_channel_available: Total channels: … Continue reading →
My Raspberry Pi had been behaving itself on the ‘hardware’ side since I took possession of it, weeks ago. After reading about limitations of USB connectivity, I obtained a reasonably-priced powered USB hub, with the intention (not surprisingly!) of connecting more things – including testing the possibility of USB sound.. So…. I connected the USB hub, and … Continue reading →
Not Linux-related this time… I should confess that I actually do use Windows 7 frequently, for HD Video processing and editing using Sony Vegas Pro and Cineform (on a stand-alone system), and for colour slide restoration using Photoshop (Win7 on VMware, on Linux).. The reason is that – simply – there is no equivalent quality software available … Continue reading →
I had intended to persevere with the Fedora 14 ‘respin’, despite it being (correctly, IMHO..) described as ‘a bit buggy’.. Performance was improved with the newer 3.1.9+ kernel image, without the debug messages, but overall the response was still very sluggish.. I selected XFCE as the UI, as I had used this – successfully – with Fedora … Continue reading →
Found the latest kernel image (still 3.1.9-based..) and associated pre-compiled modules at the git repository – https://github.com/raspberrypi/firmware – and the ‘new’ version of kernel.img does away with the annoying console debug messages.. Device still seems very slow, but maybe I’m too used to quad-core systems with masses of memory! I even tried the Debian system, as this … Continue reading →
Tried to join the Element14 ‘Programming-the-Pi’ Webinar this afternoon (April 4th), but although the java app started OK, all I saw was an ‘info’ window, and myself showing as the sole attendee! Tried with Firefox and then Chrome, but no joy… Maybe the Cisco Webex stuff they are using doesn’t work with Linux? (Oh, the irony…) (”Webinar” … Continue reading →
