Re: [gentoo-user] The Great Macbook Update 3: Qt-4.5.1 to Qt-4.5.3 blocks hell
Alan McKinnon ha scritto: Basically, the most important thing to sort out is those qt blocks. You appear to be running an arch machine as version 4.5.3-r1 wants to be merged, right? Yes, x86 (sorry, I forgot that) Trying to merge just qt-gui (or any other individual qt apps) is not really going to help much, as portage does not do a deep search. Try: emerge -avuND world and see if portage sensibly sorts out what should replace what. You might need a very recent portage for this to work automagically. Good advice. emerge -avuND world indeed seems to find the blocks as self-resolving. However, since it wants to update/install a LOT of stuff... ( Total: 414 packages (286 upgrades, 94 new, 5 in new slots, 29 reinstalls, 2 uninstalls) ) ...I would like to update the thing piece-by-piece, to troubleshoot better whatever happens. If not, you can either unmask portage, emerge portage and try again, or if you don't like that approach, you must do it the older, longer way: I could do it, if I have some safety option that allows me to downgrade portage later, in case I find problems. I am quite conservative with this system (it's a machine I use for day-to-day work) and I wouldn't like to have it borked. remove every single qt and/or qt-* package from world (qt should be treated as pure dependencies unless you are developing qt apps) unmerge *everything* in qt emerge -avuND world and let portage sort out what qt versions must be installed. Then you must remerge all of KDE4 and every other package that uses qt. Don't skimp this step becuase it 'takes a long time' - you will surely regret it (random mysterious failures etc that only go away when you finally do update all of KDE) Ok, this seems the safest option. Once qt is out of the way, proceed with any other blockers that remain Ys, qt is my mainproblem. I have another udev related block in the world update, but *seems* unrelated. Thanks! m.
Re: [gentoo-user] Re: serial port identification question
Hello James, Thanks for writing. Lots of good information in your post! I've working on porting some DOS code to Linux and (as you likely know) the code needed for serial communications differs greatly between the 2 environments. The initial problem was trying to identify COM1, COM2, etc from lots of /dev/tty?? entries. There were no /dev/ttyS? entries. This was solved thru googling and running MAKEDEV (for COM1, COM2, etc). The second problem seems to be an odd pinout. The device has an RJ11 connector and came with an RJ11 to RS232 cable. The DB9 connector is documented as TX on pin 2 and RX on pin 3 (which is normal). Connecting a breakout box, indicated TX on pin 3. With a null-modem and a loopback plug, send/receive started working using my program. Send/receive was also verified using 2 terminal sessions and commands: cat /dev/ttyS0 echo this is a test /dev/ttyS0 The tip on setserial is appreciated. I learned of stty's -F ... -a options, but didn't know of setserial. Having solved/learned the above on the Gentoo box, the next trick is getting my code to work on the embedded 486SX linux system (non-Gentoo). So far I know that programmed setting of baud rate is working (as confirmed with stty). However no data is being seen from the keypad or the two connected preamps. They should all be continuously sending data to com3, com2, and com4 (respectively). The programming world is full of strange and wonderful problems to solve, isn't it? Regards, David
[gentoo-user] Gentoo the Real-Time kernel
Has anyone tried the Real-Time kernel with Gentoo? http://rt.wiki.kernel.org/index.php/Main_Page Does anyone know if there are RT sources in an overlay anywhere? - Grant
Re: [gentoo-user] Gentoo the Real-Time kernel
It's the only kernel I've used in years. In fact I've never run gentoo-sources for any reason other than installation. With my HDSP9652 I can run sub-1 mS delays consistently. You'll find the real-time kernel in the pro-audio overlay as 'rt-sources'. You might consider joining the pro-audio overlay email list to get questions answered about configuration, not that they cannot be answered here but pretty much everyone there is running it exclusively. Note that the leading edge rt-sources kernel does tend to be a bit behind the mainline kernel so you'll want to be a bit more careful with things like closed source video drivers and the like. While not so bad now there have been times in the past where the nvidia driver did cause real-time problems. (Called 'xruns' in the audio world due to the way Jack reports these problems.) I tend to run the Open source video drivers to simply reduce the number of problems I might run into but many, many people run both the ATI and nvidia closed source drivers without any problems.

I eventually switched to ~x86 because I was tired of using versions of apps from 6 months ago... Too make a long story short, I have a new computer now and that one is going back into retirement. I may want to use it more in future and would like to know how I would go about mothballing it so that if it ever needs to be used again, bringing it up to date will be as smooth and painless as possible. If I need to resurrect it, it will probably be at least a year from now. What would you recommend? Marcus
Re: [gentoo-user] Gentoo the Real-Time kernel
It's the only kernel I've used in years. In fact I've never run gentoo-sources for any reason other than installation. With my HDSP9652 I can run sub-1 mS delays consistently. You'll find the real-time kernel in the pro-audio overlay as 'rt-sources'. You might consider joining the pro-audio overlay email list to get questions answered about configuration, not that they cannot be answered here but pretty much everyone there is running it exclusively. Note that the leading edge rt-sources kernel does tend to be a bit behind the mainline kernel so you'll want to be a bit more careful with things like closed source video drivers and the like. While not so bad now there have been times in the past where the nvidia driver did cause real-time problems. (Called 'xruns' in the audio world due to the way Jack reports these problems.) I tend to run the Open source video drivers to simply reduce the number of problems I might run into but many, many people run both the ATI and nvidia closed source drivers without any problems. Have fun, Mark Thanks Mark, I'm going to join that list. - Grant Has anyone tried the Real-Time kernel with Gentoo? http://rt.wiki.kernel.org/index.php/Main_Page Does anyone know if there are RT sources in an overlay anywhere? - Grant
Re: [gentoo-user] The current correct way to start kde 4
http://www.gentoo.org/proj/en/desktop/kde/kde4-guide.xml This is the most appropriate guide. However, I don't see any problem with just simple universal install: 1) eix kde-meta packages and choose the ones you would like to install and then simply emerge # this would pull all of the kde packages # emerge kde-meta # if you would like just the basic set of packages # emerge kdebase-meta 2) in your /etc/conf.d/xdm change the displaymanager option to simply kdm # nano /etc/conf.d/xdm ... DISPLAYMANAGER=kdm ... That'd be it :) 2009/12/28 Andrew Lowe a...@wht.com.au Hi all, I've browsed the forums, documentation etc and can find a lot of options/opinions but nothing definitive. Can someone please point me at a document that outlines the current correct way to start kde 4. I wish to have kde as the default login manager for all users of a gentoo box. Any thoughts, greatly appreciated. Andrew -- Kirill Lipatov klipa...@ku.edu

It mostly depends on what all is updated with some sort of hiccup between the time you shut it down and the time you try to update it again. If there is no major problems then it wouldn't be a issue but of there is multiple packages with issues, then you have a problem. Me, I would put it in a closet or something with a ethernet cable hooked up and just update it say once every 6 to 8 weeks. Just hope for the best after that. Dale :-) :-)

Re: [gentoo-user] The current correct way to start kde 4
well yeah. I just think that setting the kdm as the login manager is the easiest way to automatically start kde4 session after loging in. However, kdm is of course not mandatory and it can do more than just start kde4 2009/12/28 Dale rdalek1...@gmail.com Andrew Lowe wrote: Hi all, I've browsed the forums, documentation etc and can find a lot of options/opinions but nothing definitive.

Dale :-) :-) I have an emergency desktop system at work that I recently pulled out of storage to use (laptop HD died!). Once used, I spent quite a while updating it and was just going to put it aside using Dales suggestion when this thread got me thinking. I am going to clean out gnome and anything not of immediate use leaving just a bare desktop and minimal tools needed for emergency use (OO, evolution) - I'll replace gnome with fluxbox first. Then if it needs to get serious use other packages can be added on the fly. If it looks like longer term use, its easy to add gnome etc back overnight, and while continuing to use the fluxbox desktop. The minimal system should be quicker and simpler to update than a crufty system - and if you have to update much of gnome and the like, updating/reinstalling might take longer than building from scratch anyway (going by my last update to gnome :) BillK
