Best place to look for webcam drivers

by Richard Klein

I picked up a Creative Labs model VF0250 webcam, but V4L isn't detecting any devices. I googled it and it looks like gspca supported this model, but it also looks like gspca was abandoned years ago. Where would you look for answers? BTW, this is for Mint.

WLUG Meeting July 18th 2019 NOTE: Location Change: WPI Campus Center: Morgan Room

by Tim Keller

Hey Everybody! We've got a meeting this Thursday July 18th at 7PM! Location: WPI Campus Center: Morgan Room (main floor hallway to the left of the front desk) Topic: Pi 4 I thought we might talk about the pi 4. I'm going to grab the 1GB version so we'll have a sample device to poke at. I'd really like the 4GB version, but those are a bit hard to find.. I'll have it, plus a pi 3 and an assortment of older pi's as well. As usual snacks and refreshments will be provided and we'll head off for dinner to continue to the conversation. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Next Meeting moved to July 18th 2019

by Tim Keller

Hey Gang, I'm moving the meeting down a week since I'll be on vacation next week. The meeting will be on July 18th. I'd love to do a comparison of a pi 4 vs. a pi 3, but buying a 4GB pi 4 is a bit challenging... If someone already has one and could bring it, that would be awesome, if not we'll have to think of a different topic. Yeah, I know you can buy a 1GB/2GB pi 4... but really why would you do that. Thanks, Tim. WLUG President -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Dual GPU Laptops Experience?

by Dennis Payne

I bought my last laptop from System 76. It's worked well but I was thinking of upgrading. I run Fedora so I wiped the Ubuntu installed by System 76 and haven't had any problems. However my current laptop only has the Intel graphics. The new Gazelle, which is closest to what I have, includes Intel and Nvidia. Anybody have any experience with that setup with Fedora and Wayland? Does it work out of the box? Do you need to install System 76 tools to switch between the different chips? Does Nvidia with Nouveau driver give better performance over Intel? I'm unlikely to install Nvidia's closed source driver. -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

Reminder: June WLUG meeting TODAY! Topic: Side Channel Attacks.

by Tim Keller

Hey Everybody, We've got a meeting today, Thursday June 13th at 7PM! Location: WPI Campus Center Mid-Century room (rm 331) aka, the usual haunt. After last meeting we ended up having a side conversation regarding the now multiple side channel attacks that the Intel microarchitecture is vulnerable to. I thought it might be a good time to actually deep dive what these are, why they keep happening, why they're likely to continue and what efforts are being put in to try to mitigate them and the effects these migrations have on performance. As usual snacks and refreshments will be supplied and afterwards we'll head off for dinner to continue the conversation!

I picked up a free monitor today, a Samsung S24C230L. The native resolution is 1920x1080, and it's connected via DVI.

Re: PCSX2

by Dennis Payne

I started to wonder if maybe I'm not thinking about this with a eye to the future. Maintaining this will be difficult. I decided to take a look on flathub.org. It does have a flatpak for pcsx2. https://flathub.org/apps/details/net.pcsx2.PCSX2 It is listed as 1.5.0-dev. The playstation 2 bios files needed to moved to a different location. It runs about the same as the regular version. Steambot Chronicles doesn't run at full speed on my computer (about ~50% PS2 speed). The flatpak version may have been a percent or two behind but hard to say for certain. I did have problems installing it. Following the instructions on the site didn't work. The repository is added in my Gnome Software but clicking on install gave an error "Failed to install file: not supported". Not sure why that is. I ended up using the command line. flatpak install flathub net.pcsx2.PCSX2 On Sat, 2019-05-18 at 14:35 -0400, Dennis Payne via WLUG wrote: > Before the meeting on games, I tested pcsx2 thinking maybe I could > show it.

PCSX2

by Dennis Payne

Before the meeting on games, I tested pcsx2 thinking maybe I could show it. However, it was removed from rpmfusion in Fedora 30. PCSX2 is playstation 2 emulator. I have a working PS2 but the He-Man game was only released in Europe and it is region locked. The emulator finally allowed me to try the game. Since I didn't like losing that ability I've rebuilt the pcsx2 package for Fedora 30. http://identicalsoftware.com/dulsi/lzma-libs-4.32.7-21.fc30.i686.rpm http://identicalsoftware.com/dulsi/pcsx2-1.4-11.fc30.i686.rpm The src rpms are exactly the same as the files from fedora and rpmfusion. I cheated a bit in compiling the pcsx2 package. It had some errors with system headers files. Rather than create a patch to make it compile, I hacked the system header files. (It was a throw away VM because pcsx2 can't compile in 64 bit.)
