New kernels won't boot
by David A. De Graaf
My trusty old IBM T30 laptop will no longer boot with the latest
kernel-4.7.9-200.fc24.i686
kernel-4.8.4-200.fc24.i686
kernel-PAE-4.8.4-200.fc24.i686
It will still boot
kernel-4.7.7-200.fc24.i686
The grub2 menu is displayed, and after selecting the 4.7.7-200 kernel
there's a 2-3 sec delay with blinking cursor, then I'm prompted for
the encryption passphrase for the /home filesystem. Then the
voluminous messages (from removing the rhgb boot option) scroll forth
and bootup proceeds normally.
However, If I choose any of the newer kernels, the blinking cursor
remains forever; no prompt for the encryption passphrase occurs; the
keyboard is totally non-responsive. Power cycling is required to
recover.
Things I've tried:
- dnf remove <the "bad" kernel>, and reinstall it.
- Rebuild initramfs-4.8.4-200.fc24.i686.img with dracut. The new file
is only one byte bigger, probably due to a different date, and still
won't boot.
- Added the secret 'dis_ucode_ldr' boot option, as revealed in
https://www.reddit.com/r/Fedora/comments/4qrl1k/kernel_46_wont_boot_how_c...
but this seemed aimed at newer IBM laptops, and indeed, had no
effect on my T30.
- Updated the BIOS. The T30 has two components: the BIOS and the EC
(Embedded Controller). My BIOS was up to date at version 2.10
but the EC was v. 1.03, while v. 1.07 was available.
Sadly, updating to EC v. 1.07 did not alleviate the problem.
Any thoughts, shared experience, commiserations, suggestions?
What can be so different about these newer kernels?

F25 install old computer delayed after fsck
by Mayavimmer
I am trying to install F25 KDE 64 bit on an old HP Proliant with 2GB RAM
and a 2005 BIOS currently used in production (don't look at me, look at
the boss instead). The install is very very slow and took more than a
half hour to fsck the 2TB raid 1 disks. I only initially want to install
it on a free 20GB ext4 partition, no raid. Cannot unplug the 2TB disks.
Is there a way to avoid the useless half hour fsck?

3.3 gigs in /var/cache/PackageKit/24/metadata after dnf system-upgrade
by Schlaegel
I followed the instructions in the Fedora 25 Installation Guide and the DNF
system upgrade document, using `sudo dnf system-upgrade download --refresh
--releasever=25` and then the `sudo dnf system-upgrade reboot` command.
I then worked through an issue with the stock repositories and packages
causing my Nvidia graphics to lock up, and I eventually had a working
system.
After a month of updates, I started seeing warnings about the size of the
var partition. Somehow /var/cache/PackageKit/24/metadata is still there and
very large. I tried `sudo pkcon refresh force -c -1` but I still have 3.3
gigs in PackageKit's Fedora 24 directory.
What would be a good course of action?
I'm reluctant to use root to just delete the files, assuming that they are
in some PackageKit database somewhere.
Is there another step that should be added to the DNF system upgrade
document to have this directory cleaned?

Gigabyte GeForce GT 740
by François Patte
Bonjour,
I have to replace my graphic card and as the previous one was an nvidia
which has perfectly worked for 15 years, I want to remain with this brand.
Is the Gigabyte GeForce GT 740 ok to work under last version of fedora?
Thank you.

Fedora 25 GUI Problem
by Georgi Tsanov
My issue: I installed fedora 25 a few days ago alongside windows7. I had no
problems with fedora i did an update, installed nvidia drivers and all the
apps i need made the necessary configurations and everything was okey.
Today (2-3 days after the installation) when i rebooted from my windows7,
went into GRUB menu, selected fedora25, typed my HDD encryption password,
and instead of showing up the GUI login screen I get a blank(black) screen
(while my monitor is running not sleeping). When i press Ctrl+alt+F2 I can
open log in as a root/user but still no GUI, I can only terminal commands.
Here are some of the commands i have tried and did not work(not in this
particular order) "startx", "systemctl set-default graphical-target", "dnf
install gdk". Am using fedora for the first time and basically have been
using only ubuntu for a couple of months on my laptop so am quite the
newbie. Wil be thankful is someone can solve my unsolveable issue!
Hardware i am using: CPU - AMD Athlon(tm) X4 860K Quad Core Processor 3.70
GHz RAM - 8GB Graphics Card - Nvidia GeForxe GTX 960 Windows is installed
on my SSD (250 GB) Fedora isinstalled on my HDD (1TB)
Thanks in advance!

Screen rapidly blanking on and off
by Ted Roche
I've run into a problem with my Dell Inspiron where the screen blanks
every second, unless I'm typing or moving the mouse. Spinning the
mouse around the screen will keep the screen lit, while typing will
blank between keystrokes, and I'm a fair 70 wpm typist.
This ia Fedora 23 64 bit installation, and I've seen the problem on
all three of the current kernel installs,
Linux jupiter.in.tedroche.com 4.7.4-100.fc23.x86_64 #1 SMP Thu Sep 15
18:48:53 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
4.7.4, 4.7.5, and 4.7.6.
Nothing in the logs stands out and unusual.
Suggestions on what I might look at to troubleshoot ths?

I have a 3rd party app that use a Java GUI, so it won't run on a headless JVM. I had it working until I installed a different app using dnf.

I use a several Java applications, some headless, some not on various linux distros + Windows +MacOS. Over time, most apps have begun to provide their own jvm. The others use various mechanisms such as setting JVM_HOME or editing a shell script to allow user to choose a suitable JVM. I always let the distro pick the "default" Java (e.g., openJDK), and install Oracle Java when one of my apps needs something that doesn't work properly with the distro package. It is an annoyance that apps use different, poorly documented, mechanisms to control which JRE is used.
https://fedoraproject.org/wiki/Java says multiple Java versions should coexist in Fedora (use alternatives to select the one you want to be active)
