what name does com1 rs232 get in F16+ ?
by Fernando Cassia 01 Jun '12

01 Jun '12

I have a server with a good old rs232 port, namely com1 in the win32 / os2 world. I have plugged a good old real external modem (not winmodem) -a Zoltrix V90 56k- via db9 rs232 cable to the com1 port. On Fedora 16+ I get no /dev/modem device at all. Why this? If I fire up kppp and select the modem tab, under port I get a long list of meaningless names like /dev/noz0 /dev/noz1 /dev/noz2 /dev/noz3 /dev/ttyl0 /dev/ttyl1 /dev/ttyl2 /dev/ttyl3 /dev/ttyACM0 /dev/ttyACM1 /dev/ttyACM2 /dev/ttyACM3 /dev/ttyS0 /dev/ttyS1 /dev/ttyS2 /dev/ttyS3 So... is there any app/script out there that can save me the hassle of trying one by one and find a modem that answers in the com1 port? I really don' t want to know what meaningless name F16+ assigns to the port... just give me a good old /dev/modem...

Problem shutting down laptop...
by Darryl L. Pierce 01 Jun '12

01 Jun '12

I did the preupgrade yesterday on three machines without issue. On my laptop, though, I'm having a problem with shutting the laptop down now. It's a Lenovo W510+ and, during the shutdown process, when it switches to text I see an error (don't remember the exact text offhand) about shutdown having a problem. Then the laptop just stops and the CapsLock light starts blinking. At this point I have to power down the old Irish way by holding the power button. Anybody else hitting this? -- Darryl L.

VLC + projectM visualisations = segfault
by Fernando Cassia 01 Jun '12

01 Jun '12

I' m using VLC 2.01 as per the vlc-2.0.1-1.fc17.i686 RPM I quickly found that the default audio ' visualization ' plugins included with VLC 2.x suck so badly that it'd be better if they included no visualizations AT ALL. So off I went to google for better alternatives, and quickly found about ProjectM http://projectm.sourceforge.net/ which aptly describes itself as " an awesome music visualizer. There is nothing better in the world of Unix. projectM's greatness comes from the hard work of the community. Users like you can create presets that connect music with incredible visuals" And I was pleased to see that projectM is available on Fedora repos: # yum install *projectM* Loaded plugins: langpacks, presto, refresh-packagekit Package libprojectM-2.0.1-14.fc17.i686 already installed and latest version Resolving Dependencies --> Running transaction check ---> Package libprojectM-devel.i686 0:2.0.1-14.fc17 will be installed ---> Package libprojectM-qt.i686 0:2.0.1-5.fc17 will be installed ---> Package libprojectM-qt-devel.i686 0:2.0.1-5.fc17 will be installed --> Processing Dependency: qt-devel for package: libprojectM-qt-devel-2.0.1-5.fc17.i686 --> Processing Dependency: pkgconfig(QtXml) for package: libprojectM-qt-devel-2.0.1-5.fc17.i686 --> Processing Dependency: pkgconfig(QtOpenGL) for package: libprojectM-qt-devel-2.0.1-5.fc17.i686 --> Processing Dependency: pkgconfig(QtGui) for package: libprojectM-qt-devel-2.0.1-5.fc17.i686 --> Processing Dependency: pkgconfig(QtCore) for package: libprojectM-qt-devel-2.0.1-5.fc17.i686 ---> Package projectM-jack.i686 0:2.0.1-5.fc17 will be installed ---> Package projectM-libvisual.i686 0:2.0.1-6.fc17 will be installed ---> Package projectM-pulseaudio.i686 0:2.0.1-7.fc17 will be installed --> Running transaction check ---> Package qt-devel.i686 1:4.8.1-10.fc17 will be installed --> Processing Dependency: pkgconfig(xv) for package: 1:qt-devel-4.8.1-10.fc17.i686 --> Running transaction check ---> Package libXv-devel.i686 0:1.0.7-1.fc17 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: libprojectM-devel i686 2.0.1-14.fc17 fedora 13 k libprojectM-qt i686 2.0.1-5.fc17 fedora 107 k libprojectM-qt-devel i686 2.0.1-5.fc17 fedora 8.9 k projectM-jack i686 2.0.1-5.fc17 fedora 23 k projectM-libvisual i686 2.0.1-6.fc17 fedora 26 k projectM-pulseaudio i686 2.0.1-7.fc17 fedora 44 k Installing for dependencies: libXv-devel i686 1.0.7-1.fc17 fedora 38 k qt-devel i686 1:4.8.1-10.fc17 fedora 10 M Transaction Summary ================================================================================ Install 6 Packages (+2 Dependent packages) Total download size: 11 M Installed size: 33 M Is this ok [y/N]: y Downloading Packages: (1/8): libXv-devel-1.0.7-1.fc17.i686.rpm | 38 kB 00:00 (2/8): libprojectM-devel-2.0.1-14.fc17.i686.rpm | 13 kB 00:00 (3/8): libprojectM-qt-2.0.1-5.fc17.i686.rpm | 107 kB 00:00 (4/8): libprojectM-qt-devel-2.0.1-5.fc17.i686.rpm | 8.9 kB 00:00 (5/8): projectM-jack-2.0.1-5.fc17.i686.rpm | 23 kB 00:00 (6/8): projectM-libvisual-2.0.1-6.fc17.i686.rpm | 26 kB 00:00 (7/8): projectM-pulseaudio-2.0.1-7.fc17.i686.rpm | 44 kB 00:00 (8/8): qt-devel-4.8.1-10.fc17.i686.rpm | 10 MB 00:51 -------------------------------------------------------------------------------- Total 194 kB/s | 11 MB 00:55 Running Transaction Check Running Transaction Test Transaction Test Succeeded Running Transaction Installing : libXv-devel-1.0.7-1.fc17.i686 1/8 Installing : libprojectM-devel-2.0.1-14.fc17.i686 2/8 Installing : libprojectM-qt-2.0.1-5.fc17.i686 3/8 Installing : 1:qt-devel-4.8.1-10.fc17.i686 4/8 Installing : libprojectM-qt-devel-2.0.1-5.fc17.i686 5/8 Installing : projectM-pulseaudio-2.0.1-7.fc17.i686 6/8 Installing : projectM-jack-2.0.1-5.fc17.i686 7/8 Installing : projectM-libvisual-2.0.1-6.fc17.i686 8/8 Verifying : libprojectM-devel-2.0.1-14.fc17.i686 1/8 Verifying : projectM-pulseaudio-2.0.1-7.fc17.i686 2/8 Verifying : 1:qt-devel-4.8.1-10.fc17.i686 3/8 Verifying : libprojectM-qt-2.0.1-5.fc17.i686 4/8 Verifying : projectM-libvisual-2.0.1-6.fc17.i686 5/8 Verifying : libprojectM-qt-devel-2.0.1-5.fc17.i686 6/8 Verifying : libXv-devel-1.0.7-1.fc17.i686 7/8 Verifying : projectM-jack-2.0.1-5.fc17.i686 8/8 Installed: libprojectM-devel.i686 0:2.0.1-14.fc17 libprojectM-qt.i686 0:2.0.1-5.fc17 libprojectM-qt-devel.i686 0:2.0.1-5.fc17 projectM-jack.i686 0:2.0.1-5.fc17 projectM-libvisual.i686 0:2.0.1-6.fc17 projectM-pulseaudio.i686 0:2.0.1-7.fc17 Dependency Installed: libXv-devel.i686 0:1.0.7-1.fc17 qt-devel.i686 1:4.8.1-10.fc17 Complete!

F17 Gnome3 workspace names
by Greg Woods 01 Jun '12

01 Jun '12

Under F16, I was able to create a file ~/.gconf/apps/metacity/workspace_names/%gconf.xml that would allow me to name my workspaces, so they don't show up as "Workspace 1", "Workspace 2", etc. After a fresh install of F17, this is no longer working although the file is still present. Is there a way to name workspaces under Gnome3/F17? Thanks, --Greg

How to install OpenJDK6 on F17
by Fernando Lozano 01 Jun '12

01 Jun '12

Hi there, I was surprized that F17 uses OpenJDK7 by default but does not includes OpenJDK6 packages also, like F16 did. If I have some app which cannot run on Java 7, what should I do? I know I can download the proprietary JDK6 from Oracle, but I'd rather use OpenJDK. I tried installing OpenJDK6 packages from F16 but yum complains they are obsoleted by OpenJDK7. I also tried downloading IcedTea6 sources and compiling, but they stop with an "internal compiler error". Any hints? []s, Fernando Lozano

Need more info: UEFI Secure Boot in Fedora
by Edward M 01 Jun '12

01 Jun '12

Hi, I fully dont understand the approach that may be taken as workaround to USFI Secure Boot for Fedora: The last option wasn't hugely attractive, but is probably the least worst. Microsoft will be offering signing services through their sysdev portal <http://sysdev.microsoft.com>. It's not entirely free (there's a one-off $99 fee to gain access), but it's cheaper than any realistic alternative would have been. It ensures compatibility with as wide a range of hardware as possible and it avoids Fedora having any special privileges over other Linux distributions. If there are better options then we haven't found them. So, in all probability, this is the approach we'll take. Our first stage bootloader will be signed with a Microsoft key. will I need to pay $99 to use linux,etc. what about other distros? I know will be speculating at this point but wondering what could be the reprecussions if this method is taken? http://mjg59.dreamwidth.org/12368.html

F17 preupgrade
by jarmo 01 Jun '12

01 Jun '12

First, preupgrade-cli does not work, stops in some .py stuff. Can't get info, b'cause another comp. No problem, pure preupgrade went smoothly trough, new 17 all ok, so far. When closing comp kernel panic, again can't produce message here, but remember, that can't find shutdown.sh script was one of messages... So, my lap lenovo t61 works, but shutdown has problems... Doomed to be alive for ever? Heh... So have to wait other comps upgrading, probably near to 18 rc2 or something. One question, where you guys, who know something about code and so, have hurry... If you do distro for people, make sure u understand, that persons like me, 60 old want to use it. KISS, KISS, u make more crowns just waiting, not with rush. World IS IS and IS, people aren't. /* Horror, When There is no Electricity */ Jarmo

Install failed after packages installed - no f17 on grub
by William Henry 31 May '12

31 May '12

To understand what happened see my email regarding the JBoss failure. It all started there. Basically because of that failure I tried to force the JBoss-as package install under f16 kernel boot 3/4 ways through the f17 install. After successfully installing all the rest of the packages using f17 installer process, the install failed due to the rpmdb changing underneath. That was me forcing the JBoss-as installation I guess. So after the installed exited. Reboot shows no beefy miracle in the grub list. So now it's no longer the offending JBoss-as package it's more a how do I recover from this failure at this point. Or if I can't should I just install f17 from scratch and hope my /home backup will recover nicely into f17. William
