hybrid graphics laptop and nouveau
by AV 02 Nov '17

02 Nov '17

Hello, This concerns an Asus Zenbook with hybrid graphics (Intel/Nvidia). 1) There are 2 ways to deactivate the nouveau driver: by adding 'modprobe.nouveau=0' to the kernel cmd line OR by adding 'modprobe.blacklist=nouveau rd.blacklist=nouveau'. Which is to be preferred? 2) I do the above because there is as yet no Nvidia driver that gives a hybrid solution like under Windows and the Intel driver is more than enough for my needs. However when using a solution as described in 1) the Nvidia chip will still drain power. Is there anyway to deactivate the chip? (short of removing it from the motherboard if possible). AV

strange screen tearing effect
by Tim 01 Nov '17

01 Nov '17

Since updating to Fedora 26, I get a strange screen tearing effect on any moving image (scrolling webpages, watching live video, anything that moves). The effect is unnoticeable on static displayes. The effect is like this diagram: http://imgbox.com/TqED2C76 There's a portion at the top of the screen related to one moment in time, with a dividing line going across the screen, related to another moment. The really strange thing is that there's a diagonal portion to this division. The division slowly rolls down the screen, so it can be seen that the screen refresh rate is different from the source material (whatever it may be). According to driconf, which offers options I know nothing about, and offers nothing I see related to setting any vertical sync options, the graphics set is using: NV98 (nouveau) The display configurator (I'm using Mate) gives me 60 or 75 Hz refresh rates, and they will change the rate that the dividing line rolls down the screen, but not eliminate it. I'm using a LCD screen connected through a DVI cable (both ends, no conversions). Mate's display configurator says its DVI-I How can I get rid of this? -- [tim@localhost ~]$ uname -rsvp Linux 4.13.5-200.fc26.x86_64 #1 SMP Thu Oct 5 16:53:13 UTC 2017 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.

Why Fedora 26 comes with old Scala version?
by Oliver Ruebenacker 31 Oct '17

31 Oct '17

Hello, I'm just upgrading a laptop from Fedora 25 to 26. The upgrade process just announced it will downgrade Scala from 2.12 to 2.10. Why Fedora 26 comes with a very old Scala version, when the latest is Scala 2.12.4 and it is available as RPM <http://www.scala-lang.org/download/>? Thanks! Best, Oliver -- Oliver Ruebenacker Senior Software Engineer, Diabetes Portal <http://www.type2diabetesgenetics.org/>, Broad Institute <http://www.broadinstitute.org/>

Alternatives to "No Native Notifications" Firefox extension.
by Sam Varshavchik 31 Oct '17

31 Oct '17

With Firefox 57 looming on the horizon, this is the only extension that I have that won't work with it. I tinkered with XFCE's notification settings manager, until native notifications look sort of like Firefox's own notifications, but the native ones are still much more compact, take up much less screen real estate, and are much less intrusive. Anyone know of any 57+-compatible alternative, to keep using Firefox's notifications, instead of the system ones?

f26 to f26 cups sharing problem
by tar＠sonic.net 31 Oct '17

31 Oct '17

I'm having a cups sharing issue in what should be a straightforward situation: an existing f26 system (the client) trying to get a remote printer from a freshy installed f26 system (the server). cupsd.conf on the server is set to allow sharing in general and of the desired printer in particular, and the firewalls (server and client) have mdns and ipp-client ports open. Both machines are on the same internal network (192.168.1.4 and 192.168.1.6) and I can ssh between them just fine so the network is ok. On the client side, "avahi-browse -a" shows the printer from the server just fine: + enp9s0 IPv4 HP Deskjet D2500 series @ liberty Internet Printer local + enp9s0 IPv4 HP Deskjet D2500 series @ liberty _ipps._tcp local + enp9s0 IPv4 HP Deskjet D2500 series @ liberty UNIX Printer local However, "cups-browsed -v" has an issue:(running with cups-browsed.service stopped for testing) Avahi Browser: NEW: service 'HP Deskjet D2500 series @ liberty' of type '_ipp._tcp' in domain 'local' Avahi Browser: CACHE_EXHAUSTED Avahi Browser: ALL_FOR_NOW Avahi Browser: NEW: service 'HP Deskjet D2500 series @ liberty' of type '_ipps._tcp' in domain 'local' Avahi Browser: CACHE_EXHAUSTED Avahi Browser: ALL_FOR_NOW Avahi-Resolver: Failed to resolve service 'HP Deskjet D2500 series @ liberty' of type '_ipp._tcp' in domain 'local': Timeout reached listening Avahi-Resolver: Failed to resolve service 'HP Deskjet D2500 series @ liberty' of type '_ipps._tcp' in domain 'local': Timeout reached If I "systemctl restart cups.service" on the server, then retry the browse, the result is: Could not connect to the server liberty.local:631 for Deskjet-D2500-series! So it seems like the broadcast from the server is working but for some reason the server is not allowing the clien to get the additional information from port 631. Port 631 (ipp-client) is allowed by the firewall, and "systemctl stop firewalld" on the server does not change the behavior. The address "liberty.local:631" is suspect, as the server should be liberty.localdomain, but even adding liberty.local to /etc/hosts made no difference. On the server, a netstat shows Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:ipp 0.0.0.0:* LISTEN 882/cupsd tcp6 0 0 [::]:ipp [::]:* LISTEN 882/cupsd udp 0 0 0.0.0.0:ipp 0.0.0.0:* 938/cups-browsed so it sure seems like the server is listening on the right port... and this client has no problem connecting to a legacy f14 system. any clues or suggestions?

F26 Xfce install
by Robert Moskowitz 30 Oct '17

30 Oct '17

Past time to set up a F26 system with Xfce. Should have gotten off F24 months ago, but finally bought a new drive for the install... Anyway, all I see is a live image for F26 Xfce. Does the Netinstall give you the options for which desktop? Or doing an install to a clean drive work off the live ISO? I want complete control over how the partitions are set up. thanks

Bash startup files
by GianPiero Puccioni 29 Oct '17

29 Oct '17

Hi, I have a question about the system startup files for bash. The problem I had was that I set up an alias in ~/.bashrc, let's say alias ls="ls -lh" but it didn't work as "alias ls" reported alias ls='ls --color=auto' What happens is that at the end ~/.bashrc sources /etc/bashrc which sources /etc/profile.d/*.sh that redefine "ll". This happens on F24, F25, F26 and CentOS.... Easy to correct, but the question is: is that right? None of the examples I found on line does that and /etc/profile.d/*.sh are already sourced by /etc/profile (which is the first startup file read on login). Is this a quirk of RedHat or an error that still remains in the files or what? GianPiero
