  1. Interesting item about gcc. I've had a few issues trying to compile spidermonkey on the odroid N2. It took hours and tons of crashes. I had enabled the mix-ins for plasma which brought in that program that would not compile. I am not sure if it was compiled cleanly, anyhow it installed which enabled the rest to compile. What exactly does that buggy software do? Why is it required to get plasma support? I am not a big fan of gnome 3 so my only choice left appears to be kde. The goal is to have a decent desktop on wayland, a friend told me that I could setup kde to look just like my mac so that would work for me. I stopped using gnome long ago when they switched from 2.x to 3.x. Unfortunately mate doesn't work on wayland. My next task will be to swap the EGL stuff to use the binary blob instead of those of mesa, any idea on an easy way to do that? The eselect approach might have been a solution but the new way woudl make that impossible, or could I easily modify that program to use the binary blobs from ARM? Odroid tells us that ARM has decided to no longer support xorg so on those embedded boards wayland is the only way. Same happened last year with TI about the imagination GPU. If I enable mesa none of the GPU stuff would work. Is there a way to completely disable xorg and still be able to run gnome or kde on Funtoo? That can be very important for my Beagleboard X15 and Beaglebone-AI so I can use the EGL from Imagination. With yocto I have to disable mesa to get that to work. On funtoo mesa is called and if I try to uninstall it I get tons of error messages claiming that it is needed. Michel
  2. I have added info for using the same stage3 for the Beagleboard X15. You just need to add the missing device tree files. It uses the u-boot and kernel from digi-key eewiki which doesn't seem to support EGL from imagination When I get some time I will update it with one that does, beagleboard group seems to only want free stuff. The problem like with most arm board, if you only want that you are giving up on all the power of the video processors. I have been busy with my odroid boards so it will take a few weeks before I implement that. Note that if you use the free driver for the 2D GPU you can get a decent xorg. If you do that and want lazarus you can use my overlay to compile free pascal and lazarus. Give me a message if you go that route. I haven't it documented yet.
  3. I have two Corsair coolers, an H110i and H115i PRO. I was thinking that my H110i was on the way out because it makes so much noise so I got an H115i PRO. As I read on the net, this one may just be just as loud. Apparently you need to run some windows software to run this. Is it possible to run this from Virtual Box? Better yet, is there some software for Linux that I can install? I used to have a few systems on my linux computer, gentoo, funtoo, fedora, SuSE, Arch Linux, Mint, Ubuntu and Debian. Now I only have Funtoo and use the space on the other hard disks for video and my embedded Linux stuff. Every time I create a yocto tree, it takes an awful lot of space. I have OS/2, e-comstation and windows 10 installed with VirtualBox. I rarely ever use windows, when I need to do graphics or CAD, the Mac is a better choice. The only reason I have windows is when I need to do some work with Cypress, they do not support the MAC or Linux, only windows. They are afraid to be copied by TI which seems to be working on similar stuff. Michel
  4. How do I set funtoo so I would be able to run 32 bit arm applications on 64 bit arm OS? Target is Odroid N2. Michel
  5. I have published on my web site a Stage3 for Funtoo for the BeagleBone-AI, the AI stands for Artificial Intelligence. This board uses an AM5729 processor which is similar to the DRA752 and AM5728. The main difference with the AM5728 is the added coprocessor that is used for artificial intelligence It has a similar connector to the one from the beaglebone black. I use the kernel 4.14.108-ti-r114, I compiled it with the Linaro compiler as done on EEWIKI because it won't compile with the Funtoo gcc 9.1.1 I had no problem compiling u-boot with the funtoo gcc I will be creating several ebuilds for support that is missing for this board. I will publish those on my site. I haven't updated my funtoo page yet, when I get time I will put some information there as well. http://suzielinux.com
  6.

  7. I have created a stage3 for the Beaglebone AI and I have an issue with the boot. I have created a minimal boot with ubuntu 18.04 and do not have that issue with it. It looks like it is taking around 2 minutes for random to be done. I haven't tried with the Beagleboard X15 with this kernel. I use kernel 4.9 on the Beagleboard X15 with no such issue. Both boards use the same processor (Texas Instruments AM5729) I use the same kernel and u-boot with both suzie ~ # uname -r 4.14.108-ti-r114 U-Boot 2019.07-rc4 (Aug 25 2019 - 17:53:15 -0400) CPU : DRA752-GP ES2.0 Model: BeagleBoard.org BeagleBone AI Board: BeagleBone AI REV A DRAM: 1 GiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 CTRL_CORE_PAD_I2C1_SDA: 0x00060000 CTRL_CORE_PAD_I2C1_SCL: 0x00060000 CTRL_CORE_PAD_GPMC_A0: 0x00060007 CTRL_CORE_PAD_GPMC_A1: 0x00060007 CTRL_CORE_PAD_VIN2A_D4: 0x0005000f CTRL_CORE_PAD_VIN2A_D5: 0x0005000f CM_L4PER_GPIO7_CLKCTRL: 0x00000001 CM_L4PER_I2C1_CLKCTRL: 0x00000002 CM_L4PER_I2C4_CLKCTRL: 0x00000002 CM_L4PER_L4_PER1_CLKCTRL 0x00000001 PM_L4PER_I2C1_WKDEP 0x0000b000 RM_L4PER_I2C1_CONTEXT 0x00000002 PM_L4PER_I2C4_WKDEP 0x0000b000 RM_L4PER_I2C4_CONTEXT 0x00000001 BeagleBone: cape eeprom: i2c_probe: 0x54 Checking (ret 1 bus works) I2C1 bus. ret 1 Checking (ret 1 bus works) I2C4 bus. ret 1 BeagleBone: cape eeprom: i2c_probe: 0x55 Checking (ret 1 bus works) I2C1 bus. ret 1 Checking (ret 1 bus works) I2C4 bus. ret 1 BeagleBone: cape eeprom: i2c_probe: 0x56 Checking (ret 1 bus works) I2C1 bus. ret 1 Checking (ret 1 bus works) I2C4 bus. ret 1 BeagleBone: cape eeprom: i2c_probe: 0x57 Checking (ret 1 bus works) I2C1 bus. ret 1 Checking (ret 1 bus works) I2C4 bus. ret 1 Net: Warning: ethernet@48484000 using MAC address from ROM eth0: ethernet@48484000 Press SPACE to abort autoboot in 1 seconds usb_boot is currently disabled scsi_boot is currently disabled switch to partitions #0, OK mmc0 is current device Partition Map for MMC device 0 -- Partition Type: DOS Part Start Sector Num Sectors UUID Type 1 8192 124727296 44a48d0d-01 83 Boot Scanning mmc device 0 Checking for: /uEnv.txt ...

  8. Has anyone go a ebuild for asciidoctor-pdf ? I found one on the net but it is using old stuff from gentoo and requires files that are not supported by funtoo., Or is there a way to use ascidoctor to create a pdf without this program. I am not familiar with that ruby program and have more important tasks right now. The guys at Beagleboard use this program to generate a pdf file. I guess I could change the makefile to generate an html file instead and could technically generate a pdf file later. Michel
  9. I saw that ubuntu has mate on Wayland, Is there any funtoo plan for mate Wayland? Eventually using X11 on any ARM device won't make any sense as arm has decided to no longer support X11 for their GPU. TI has started some with the Imagination GPU a few years back and abandoned it. The futur being Wayland. On that mate Wayland from ubuntu, can it be run without any X11 support? On Beagle board X15 and Beaglebone AI I can have X11 2D GPU support since there is an open source driver but no 3D, I would like to use mate on Wayland on those. With the Odroid N2 I cannot get GPU support at all for X11. Odroid says that they will have good Wayland support in a few months. A side question, I am creating stage 3 for the Beagleboard X15 and Beaglebone AI, how can I get them to Funtoo? I will have them on my website when they are completed. I have been a bit busy with yocto but should get some time for funtoo in the next few weeks. Michel
  10. On Mate I was able to get the tile to change when emerging something, how do you do that in kconsole on kde?
  11. I got it fixed by running kde with startx and running the system settings. Now I got to figure out how to get a good resolution on the 1080 monitor that doesn't look like a vic20 resolution. Setting the 4k monitor DPI to 130 from 96 make the display on the 1080 monitor unacceptable. One thing amusing, I am labeled as newbie which is a bit off considering that I have been using gentoo for many years and Funtoo for the past 2-3 years I started Linux with Yggdrasil Linux back in the 90s when IBM announced the end of their OS/2 support. I earn my living with embedded Linux.
  12. After I got sddm-greeter binary I got this localhost ~ # /usr/bin/sddm-greeter --test-mode --theme /usr/share/sddm/themes/elarun/ Abandon
  13. localhost ~ # sddm-greeter --test-mode --theme /usr/share/sddm/themes/elarun -bash: sddm-greeter : commande introuvable
  14. localhost ~ # ldd /usr/lib64/qt5/plugins/platforms/libqxcb.so | grep 'not found' localhost ~ # equery b libqxcb.so * Searching for libqxcb.so ... dev-qt/qtgui-5.12.3-r1 (/usr/lib64/qt5/plugins/platforms/libqxcb.so)
  15. I have no problem running kde with startx but sddm or lightdm cannot load it. I had no problem with lightdm when I was running mate I thought at first that it was just refusing my password but when I entered a bogus password I had a different result. The password is accepted and I get a black screen and it gets back to the prompt. I setup the autologin and still get to the prompt asking for the login and password. I tried the theme and got some errors, so it looks like it cannot load the themes I followed the wiki closely so I assumed that I have all the needed files, what is missing? The monitor is a 4k monitor. michel@localhost ~ $ sddm-greeter --theme /usr/share/themes/breeze [23:32:02.279] (II) GREETER: High-DPI autoscaling not Enabled [23:32:02.280] (WW) GREETER: could not connect to display [23:32:02.280] (II) GREETER: Could not load the Qt platform plugin "xcb" in "" even though it was found.
